9a3170bf77 rbd: provide a way to disable the auto fallback to nbd mounter
This change allows the user to choose not to fallback to NBD mounter
when some ImageFeatures are absent with krbd driver, rather just fail
the NodeStage call.

b132696e54 rbd: note that thick-provisioning is deprecated
Thick-provisioning was introduced to make accounting of assigned space
for volumes easier. When thick-provisioned volumes are the only consumer
of the Ceph cluster, this works fine. However, it is unlikely that this
is the case. Instead, accounting of the requested (thin-provisioned)
size of volumes is much more practical as different types of volumes can
be tracked.

OpenShift already provides cluster-wide quotas, which can combine
accounting of requested volumes by grouping different StorageClasses.

In addition to the difficult practise of allowing only thick-provisioned
RBD backed volumes, the performance makes thick-provisioning
troublesome. As volumes need to be completely allocated, data needs to
be written to the volume. This can take a long time, depending on the
size of the volume. Provisioning, cloning and snapshotting becomes very
much noticeable, and because of the additional time consumption, more
prone to failures.

4937e59c4d rbd: add backwards compatible encryption in NodeStageVolume
When a volume was provisioned by an old Ceph-CSI provisioner, the
metadata of the RBD image will contain `requiresEncryption` to indicate
a passphrase needs to be created. New Ceph-CSI provisioners create the
passphrase in the CreateVolume request, and set `encryptionPrepared`
instead.

When a new node-plugin detects that `requiresEncryption` is set in the
RBD image metadata, it will fallback to the old behaviour.

In case `encryptionPrepared` is read from the RBD image metadata, the
passphrase is used to cryptsetup/format the image.

669dc4536f Reduce encryption KMS configuration SC parameters
* moves KMS type from StorageClass into KMS configuration itself
 * 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.

fa68c35f3b Support mounting and deleting version 1.0.0 RBD volumes
This commit adds support to mount and delete volumes provisioned by older
plugin versions (1.0.0) in order to support backward compatibility to 1.0.0
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 #378

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 #270

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 #382)
- 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 #359)
- 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
