* 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)

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
the full feature that adds encryption with passphrase stored in secrets.

Skip zeroing of the journal on freshly created images. As only dynamic
PVs are supported, it is fine to assume that existingFormat == "" image
has never been mapped and written to before.
lazy_itable_init is enabled by default, passing it for consistency with

Currently rbd CSI plugin uses formatAndMount of
mount.SafeFormatAndMount. This does not allow to pass or use
specific formatting arguments with it. This patch introduce
RBD specific formatting options with both xfs and ext4,
for example: -E no-discard with ext4 and -k option with
XFS to boost formatting performance of RBD device.

Image deletion takes time proportional to the size of the
image. Hence, ceph manager is enhanced to support async
deletion of an image, or rather passing the task of
deleting an image to the ceph manager.
This commit leverages the ceph manager enhancement in the CSI code.
NOTE: This is tested against a ceph cluster that is running
Ceph master version of the code. Once other releases
catch up in terms of the feature, the optimization would be
available to the CSI driver as well.

In unstage we now adhere to the transaction (or order of steps)
done in Stage. To enable this we stash the image meta data
into a local file on the staging path for use with unstage
request.
This helps in unmapping a stale map, in case the mount or
other steps in the transaction are complete.

This commit moves the mounting of a block volumes and filesystems
to a sub-file (already the case) or a sub-dir within the staging
path.
This enables using the staging path to store any additional data
regarding the mount. For example, this will be extended in the
future to store the fsid of the cluster, and maybe the pool name
to map unmap requests to the right image.
Also, this fixes the noted hack in the code, to determine in a
common manner if there is a mount on the passed in staging path.

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.

File descriptors in use to parse errors from a few command
invocations were incorrect. This led to inability to detect
certain errors cases and act accordingly.
One of the easiest noticeable issues was when an image is deleted
but its RADOS keys and maps are still intact. In such cases
the DeleteVolume call always errored out unable to find the
image rather than, proceed with cleaning up the RADOS objects
and returning a success.
The original method of using stdout was incorrect, as the command
was tested from within a shell script and the scripts STDIN/OUT/ERR
was redirected to understand behavior. This is now tested using just
the CLI in question, and also examining Ceph code, and further
testing a couple of edge conditions by deleting backing images
for PVs
