a1de56dbd3 tests: in case 'go test' is run in a container, skip TestGetPIDLimit()
In (standard, non-privileged) container environments the /sys/fs/cgroup
mountpoint is not available. This would cause the tests to fail, as
TestGetPIDLimit() tries to write to the cgroup configuration.

The test will work when run as root on a privileged container or
directly on a host (as Travis CI does).

Setting the CEPH_CSI_RUN_ALL_TESTS environment variable to a non-empty
value will cause the test to be executed.

 * updates omapval used to identify KMS to only it's ID without the type

why?

1. when using multiple KMS configurations (not currently supported)
automated parsing of kms configuration will be failing because some
entries in configs won't comply with the requested type
2. less options are needed in the StorageClass and less data used to
identify the KMS

31648c8feb provisioners: add reconfiguring of PID limit
The container runtime CRI-O limits the number of PIDs to 1024 by
default. When many PVCs are requested at the same time, it is possible
for the provisioner to start too many threads (or go routines) and
executing 'rbd' commands can start to fail. In case a go routine can not
get started, the process panics.

The PID limit can be changed by passing an argument to kubelet, but this
will affect all pids running on a host. Changing the parameters to
kubelet is also not a very elegant solution.

Instead, the provisioner pod can change the configuration itself. The
pod is running in privileged mode and can write to /sys/fs/cgroup where
the limit is configured.

With this change, the limit is configured to 'max', just as if there is
no limit at all. The logs of the csi-rbdplugin in the provisioner pod
will reflect the change it makes when starting the service:

    $ oc -n rook-ceph logs -c csi-rbdplugin csi-rbdplugin-provisioner-0
    ..
    I0726 13:59:19.737678       1 cephcsi.go:127] Initial PID limit is set to 1024
    I0726 13:59:19.737746       1 cephcsi.go:136] Reconfigured PID limit to -1 (max)
    ..

It is possible to pass a different limit on the commandline of the
cephcsi executable. The following flag has been added:

    --pidlimit=<int>       the PID limit to configure through cgroups

This accepts special values -1 (max) and 0 (default, do not
reconfigure). Other integers will be the limit that gets configured in
cgroups.

created volumes.

It adds back the ability to specify where older meta data was specified, using
the metadatastorage option to the plugin. Further, using the provided meta data
to mount and delete the older volumes.

It also supports a variety of ways in which monitor information may have been
specified (in the storage class, or in the secret), to keep the monitor
information current.

Testing done:
- Mount/Delete 1.0.0 plugin created volume with monitors in the StorageClass
- Mount/Delete 1.0.0 plugin created volume with monitors in the secret with
  a key "monitors"
- Mount/Delete 1.0.0 plugin created volume with monitors in the secret with
  a user specified key
- PVC creation and deletion with the current version (to ensure at the minimum
  no broken functionality)
- Tested some negative cases, where monitor information is missing in secrets
  or present with a different key name, to understand if failure scenarios work
  as expected

Updates 

Follow-up work:
- Documentation on how to upgrade to 1.1 plugin and retain above functionality
  for older volumes

c5762b6b5c Modify RBD plugin to use a single ID and move the id and key into the secret
RBD plugin needs only a single ID to manage images and operations against a
pool, mentioned in the storage class. The current scheme of 2 IDs is hence not
needed and removed in this commit.

Further, unlike CephFS plugin, the RBD plugin splits the user id and the key
into the storage class and the secret respectively. Also the parameter name
for the key in the secret is noted in the storageclass making it a variant and
hampers usability/comprehension. This is also fixed by moving the id and the key
to the secret and not retaining the same in the storage class, like CephFS.

Fixes 

Testing done:
- Basic PVC creation and mounting

b9cd0e18ad Make CephFS plugin stateless reusing RADOS based journal scheme
This is a part of the stateless set of commits for CephCSI.

This commit removes the dependency on config maps to store cephFS provisioned
volumes, and instead relies on RADOS based objects and keys, and required
CSI VolumeID encoding to detect the provisioned volumes.

Changes:
- Provide backward compatibility to provisioned volumes by older plugin versions (1.0.0 or older)
- Remove Create/Delete support for statically provisioned volumes (fixes )
- Added namespace support to RADOS OMaps and used the same to store RADOS CSI objects and keys in the CephFS metadata pool
- Added support to mention fsname for CephFS provisioning (fixes )
- Changed field name in CSI Identifier to 'location', to denote a pool or fscid
- Updated mounter cache to use new scheme
- Required Helm manifests are updated
- Required documentation and other manifests are updated
- Made driver option 'metadatastorage' as optional, as fresh installs do not need to specify the same

Testing done:
- Create/Mount/Delete PVC
- Create/Delete 5 PVCs
- Mount version 1.0.0 PVC
- Delete version 1.0.0 PV
- Mount Statically defined PV/PVC/Pod
- Mount Statically defined version 1.0.0 PV/PVC/Pod
- Delete Statically defined version 1.0.0 PV/PVC/Pod
- Node restart when mounted to test mountcache
- Use InstanceID other than 'default'
- RBD basic round of tests, as namespace is added to OMaps
- csitest against ceph-fs plugin
  - NOTE: CephFS plugin still does not detect and address already created
  volumes but of a different size
- Test not providing any value to the metadata storage parameter

currently, we have 3 docker files(cephcsi,rbd,cephfs) in the ceph-csi repo.
[commit ](85e121ebfe)
added by John to build a single image which can act as rbd or
cephfs based on the input configuration.

This PR updates the makefile and kubernetes templates to use
the unified image and also its deletes the other two dockerfiles.

d02e50aa9b Removed config maps and replaced with rados omaps
Existing config maps are now replaced with rados omaps that help
store information regarding the requested volume names and the rbd
image names backing the same.

Further to detect cluster, pool and which image a volume ID refers
to, changes to volume ID encoding has been done as per provided
design specification in the stateless ceph-csi proposal.

Additional changes and updates,
- Updated documentation
- Updated manifests
- Updated Helm chart
- Addressed a few csi-test failures

2064e674a4 Addressed using k8s client APIs to fetch secrets
Based on the review comments addressed the following,
- Moved away from having to update the pod with volumes
when a new Ceph cluster is added for provisioning via the
CSI driver

- The above now used k8s APIs to fetch secrets
  - TBD: Need to add a watch mechanisim such that these
secrets can be cached and updated when changed

- Folded the Cephc configuration and ID/key config map
and secrets into a single secret

- Provided the ability to read the same config via mapped
or created files within the pod

Tests:
- Ran PV creation/deletion/attach/use using new scheme
StorageClass
- Ran PV creation/deletion/attach/use using older scheme
to ensure nothing is broken
- Did not execute snapshot related tests

97f8c4b677 Provide options to pass in Ceph cluster-id
This commit provides the option to pass in Ceph cluster-id instead
of a MON list from the storage class.

This helps in moving towards a stateless CSI implementation.

Tested the following,
- PV provisioning and staging using cluster-id in storage class
- PV provisioning and staging using MON list in storage class

Did not test,
- snapshot operations in either forms of the storage class

b5b8e46460 Add multiNodeWritable option for RBD Volumes
This change adds the ability to define a `multiNodeWritable` option in
the Storage Class.

This change does a number of things:
1. Allow multi-node-multi-writer access modes if the SC options is
enabled
2. Bypass the watcher checks for MultiNodeMultiWriter Volumes
3. Maintains existing watcher checks for SingleNodeWriter access modes
regardless of the StorageClass option.
