eea97ca014 util: move GetID() from EncryptionKMS to VolumeEncryption
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.

9317e2afb4 util: rewrite GetKMS() to use KMS provider plugin API
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.

9ac7f56400 util: move existing KMS implementations to the DEKStore interface
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.

dc81e001cf cleanup: remove unused MissingPassphrase error type
Storing a passphrase is now done while the volume is created. There is
no need to (re)generate a passphrase when it can not be found.

582d004ca5 util: store EnvVaultInsecure as string, not bool
The configuration option `EnvVaultInsecure` is expected to be a string,
not a boolean. By converting the bool back to a string (after
verification), it is now possible to skip the certificate validation
check by setting `vaultCAVerify: false` in the Vault configuration.

8f91c672d4 util: add EncryptionKMS.Destroy()
Add a new method to the EncryptionKMS interface so that resources can be
freed when EncryptionKMS instances get freed.

With the move to using the libopenstorage API, a temporary file needs to
store the optional CA certificate. The Destroy() method of the
vaultConnection type now removes this file.

The rbdVolume uses the EncryptionKMS type now, so call the new Destroy()
method from withing rbdVolume.Destroy().

d28a5a5f23 util: pass map[string]interface{} to initialize KMS
This makes it possible to pass a more complex configuration to the
initialize functions for KMS's. The upcoming VaultTokensKMS can use
overrides for configiration options on a per tenant basis. Without this
change, it would not be possible to consume the JSON configuration file.
