nlreturn linter requires a new line before return
and branch statements except when the return is alone
inside a statement group (such as an if statement) to
increase code clarity. This commit addresses such issues.

This commit adds capability to `metadata` encryption
to be able to fetch `encryptionPassphrase` from user
specified secret name and namespace(if not specified,
will default to namespace where PVC was created).
This behavior is followed if `secretName` key is found
in the encryption configuration else defaults to fetching
`encryptionPassphrase` from storageclass secrets.
Closes: 2107

There is no need for each EncryptionKMS to implement the same GetID()
function. We have a VolumeEncryption type that is more suitable for
keeping track of the KMS-ID that was used to get the configuration of
the KMS.
This does not change any metadata that is stored anywhere.

GetKMS() is the public API that initilizes the KMS providers on demand.
Each provider identifies itself with a KMS-Type, and adds its own
initialization function to a switch/case construct. This is not well
maintainable.
The new GetKMS() can be used the same way, but uses the new kmsManager
interface to create and configure the KMS provider instances.
All existing KMS providers are converted to use the new kmsManager
plugins API.

This new KMS is based on the (default) SecretsKMS, but instead of using
the passphrase for all volumes, the passphrase is used to
encrypt/decrypt a Data-Encryption-Key that is stored in the metadata of
the volume.

Use DEKStore API for Fetching and Storing passphrases.
Drop the fallback for the old KMS interface that is now provided as
DEKStore. The original implementation has been re-used for the DEKStore
interface.
This also moves GetCryptoPassphrase/StoreNewCryptoPassphrase functions
to methods of VolumeEncryption.

Prepare for grouping encryption related functions together. The main
rbdVolume object should not be cluttered with KMS or DEK procedures.

Prepared for an enhanced API to communicate with a KMS and keep the DEK
storage separate. The crypto.go file is already mixed with different
functions, so moving the KMS part into its own file, just like we have
for Hashicorp Vault KMS's.
