When the KMS configuration can not be found, it is useful to know what
configurations are available. This aids troubleshooting when typos in
the KMS ID are made.

Amazon KMS expects a Secret with sensitive account and key information
in the Kubernetes Namespace where the Ceph-CSI Pods are running. It will
fetch the contents of the Secret itself.

These functions can now be re-used easier. The Amazon KMS needs to know
the Namespace of the Pod for reading a Secret with more key/values.

When using .BinaryData, the contents of the configuration is not parsed
correctly. Whereas the parsing works fine whet .Data is used.

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.

The KMSProvider struct is a simple, extendable type that can be used to
register KMS providers with an internal kmsManager.
Helper functions for creating and configuring KMS providers will also be
located in the new kms.go file. This makes things more modular and
better maintainable.
