1. fix: retry non-idempotent long-running RPCs …

   RPCs returning a long-running operation, such as CreateDatabase,
   CreateBackup and RestoreDatabase, are non-idempotent and cannot be
   retried automatically by gax. This means that these RPCs sometimes fail
   with transient errors, such as UNAVAILABLE or DEADLINE_EXCEEDED. This
   change introduces automatic retries of these RPCs using the following
   logic:
   1. Execute the RPC and wait for the operation to be returned.
   2. If a transient error occurs while waiting for the operation, the
      client library queries the backend for the corresponding operation.
      If the operation is found, the resumes the tracking of the existing
      operation and returns that to the user.
   3. If no corresponding operation is found in step 2, the client library
      retries the RPC from step 1.
   
   Fixes GoogleCloudPlatform/java-docs-samples#2571
