This commit adds an admin API route and handler for requesting status information about a KMS key. Therefore, the client specifies the KMS key ID (when empty / not set the server takes the currently configured default key-ID) and the server tries to perform a dummy encryption, re-wrap and decryption operation. If all three succeed we know that the server can access the KMS and has permissions to generate, re-wrap and decrypt data keys (policy is set correctly).
