* 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)

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.

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
