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. Signed-off-by: Niels de Vos <ndevos@redhat.com>
