This is the initial step for improving performance during provisioning
of CSI volumes backed by RBD.
While creating a volume, an existing connection to the Ceph cluster is
used from the ConnPool. This should speed up the creation of a batch of
volumes significantly.
Updates: #449

By using the ConnPool it is not needed to re-connect every time to the
Ceph cluster when (rbd) operations are executed through the go-ceph/rbd
API.

If a CreateVolume call is interrupted,
post creating the required CSI journal entries,
but prior to creating the backing CephFS subvolume,
then a subsequent CreateVolume call will return
a valid response with a VolumeID that has
it's backing image missing. This PR adds a check
for backend image, if image notfound it deletes the
reserved keys in omap.

* 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

- adds proposal document for PVC encryption from PR448
- adds per-volume encription by generating encryption passphrase
for each volume and storing it in a KMS
- adds HashiCorp Vault integration as a KMS for encryption passphrases
- avoids encrypting volume second time if it was already encrypted but
no file system created
- avoids unnecessary checks if volume is a mapped device when encryption
was not requested
- prevents resizing encrypted volumes (it is not currently supported)
- prevents creating snapshots from encrypted volumes to prevent attack
on encryption key (security guard until re-encryption of volumes
implemented)

Added checks in DeleteVolume RPC, for image missing errors, and
taking appropriate actions to cleanup the CSI reservations.
Further removed forcing a volume purge, and instead added checks
for missing volume errors in purgeVolume.
This should now fix issues where an continuation of an interrupted
DeleteVolume call, that only deleted the backing volume, will
proceed and not error out.

Adds encryption in StorageClass as a parameter. Encryption passphrase is
stored in kubernetes secrets per StorageClass. Implements rbd volume
encryption relying on dm-crypt and cryptsetup using LUKS extension
The change is related to proposal made earlier. This is a first part of

Linux kernel 4.17.0 adds support for quota with CephFS. Without quota,
it is not possible to fullfill the requirements of the CSI Spec and
guarantee sufficient space on the filesystem for a volume. With this in
mind, usage of the kernel client is only allowed with kernel 4.17.0 or
newer.
However, some Linux vendors backport features and patches to their
Enterprise products. These kernels may have an older version, but do
support quota. One of these is the kernel that comes with RHEL-7.7.
By comparing the current running version of the Linux kernel against
known versions that support quota, we can now automatically decide to
use the kernel client, or not.
Note that this does not change the 'forcekernelclient' parameter. The
parameter is still available and can be used for kernels that are not in
the 'known to support quota list'. Or users can pass the parameter to
use a CephFS kernel client that does not support quota.

mount.SafeFormatAndMount. This does not allow to pass or use
