Google Cloud Key Management EKM Service
Manages external cryptographic keys and operations using those keys.
Implements a REST model with the following objects:
Verifies that Cloud KMS can successfully connect to the external key
manager specified by an EkmConnection.
If there is an error connecting to the EKM, this method returns a
FAILED_PRECONDITION status containing structured information as described
at https://cloud.google.com/kms/docs/reference/ekm_errors.
