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

b318964af5 issue #91
issue #217

Goal

we try to solve when csi exit unexpect, the pod use cephfs pv can not auto recovery because lost mount relation until pod be killed and reschedule to other node. i think this is may be a problem. may be csi plugin can do more thing to remount the old path so when pod may be auto recovery when pod exit and restart, the old mount path can use.

NoGoal

Pod should exit and restart when csi plugin pod exit and mount point lost. if pod not exit will get error of **transport endpoint is not connected**.

implment logic

csi-plugin start:

	1. load all MountCachEntry  from node local dir
	2. check if volID exist in cluster, if no we ignore this entry, if yes continue
	3. check if stagingPath exist, if yes we mount the path
	4. check if all targetPath exist, if yes we binmount to staging path

NodeServer:

1. NodeStageVolume: add MountCachEntry on local dir include readonly attr and ceph secret
2. NodeStagePublishVolume: add pod bind mount path to MountCachEntry  and persist local dir
3. NodeStageunPublishVolume: remove pod bind mount path From MountCachEntry  and persist local dir
4. NodeStageunStageVolume: remove MountCachEntry  from local dir

6ec1196f47 Rework multi-node-multi-writer feature
This commit reverts the initial implementation of the
multi-node-multi-writer feature:
  commit: b5b8e46460

It replaces that implementation with a more restrictive version that
only allows multi-node-multi-writer for volumes of type `block`

With this change there are no volume parameters required in the stoarge
class, we also fail any attempt to create a file based device with
multi-node-multi-write being specified, this way a user doesn't have to
wait until they try and do the publish before realizing it doesn't work.

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.

403cad682c rbd: protect against concurrent gRPC calls
The timeout value in external-provisioner is fairly low. It's not
uncommon that it times out and retries before the rbdplugin is done
with CreateVolume. rbdplugin has to serialize calls and ensure that
they are idempotent to deal with this.

25e3a961c3 rbdplugin: idempotent DeleteVolume
When the initial DeleteVolume times out (as it does on slow clusters
due to the low 10 second limit), the external-provisioner calls it
again. The CSI standard requires the second call to succeed if the
volume has been deleted in the meantime. This didn't work because
DeleteVolume returned an error when failing to find the volume info
file:

  rbdplugin: E1008 08:05:35.631783       1 utils.go:100] GRPC error: rbd: open err /var/lib/kubelet/plugins/csi-rbdplugin/controller/csi-rbd-622a252c-cad0-11e8-9112-deadbeef0101.json/open /var/lib/kubelet/plugins/csi-rbdplugin/controller/csi-rbd-622a252c-cad0-11e8-9112-deadbeef0101.json: no such file or directory

The fix is to treat a missing volume info file as "volume already
deleted" and return success. To detect this, the original os error
must be wrapped, otherwise the caller of loadVolInfo cannot determine
the root cause.

Note that further work may be needed to make the driver really
resilient, for example there are probably concurrency issues.
But for now this fixes: #82

The driver will now probe for either ceph fuse/kernel every time

This also affects CreateVolume/DeleteVolume where the mounting
was hard-coded to ceph kernel client till now - mounter configuration
and probing are now honored.
