bd204d7d45 Use --keyfile option to pass keys to all Ceph CLIs
Every Ceph CLI that is invoked at present passes the key via the
--key option, and hence is exposed to key being displayed on
the host using a ps command or such means.

This commit addresses this issue by stashing the key in a tmp
file, which is again created on a tmpfs (or empty dir backed by
memory). Further using such tmp files as arguments to the --keyfile
option for every CLI that is invoked.

This prevents the key from being visible as part of the argument list
of the invoked program on the system.

Fixes: #318

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

c4a3675cec Move locks to more granular locking than CPU count based
As detailed in issue #279, current lock scheme has hash
buckets that are count of CPUs. This causes a lot of contention
when parallel requests are made to the CSI plugin. To reduce
lock contention, this commit introduces granular locks per
identifier.

The commit also changes the timeout for gRPC requests to Create
and Delete volumes, as the current timeout is 10s (kubernetes
documentation says 15s but code defaults are 10s). A virtual
setup takes about 12-15s to complete a request at times, that leads
to unwanted retries of the same request, hence the increased
timeout to enable operation completion with minimal retries.

Tests to create PVCs before and after these changes look like so,

Before:
Default master code + sidecar provisioner --timeout option set
to 30 seconds

20 PVCs
Creation: 3 runs, 396/391/400 seconds
Deletion: 3 runs, 218/271/118 seconds
  - Once was stalled for more than 8 minutes and cancelled the run

After:
Current commit + sidecar provisioner --timeout option set to 30 sec
20 PVCs
Creation: 3 runs, 42/59/65 seconds
Deletion: 3 runs, 32/32/31 seconds

bc39c523b7 Fix returning success from DeleteSnapshot for stale requests
Also reduced code duplication in fetching pool list from Ceph.

DeleteSnapshot like DeleteVolume, should return a success when it
detects that the snapshot keys are missing from the RADOS OMaps that
store the snapshot UUID to request name mapping.

This was missing in the code, and is now added.

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

Testing done:
- Basic PVC creation and mounting

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

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.
