      Description

      Now that Kudu has a replay cache, we should use it for master DDL operations like CreateTable(), AlterTable(), and DeleteTable(). To do this we'll need to add some client-specific RPC state into the write that the leader master replicates to its followers, and use that state when an RPC is retried.

      Some tests (e.g. master-stress-test) have workarounds that should be removed when this bug is fixed.
