Zaiming (Stone) Shi 2065be569e fix(emqx_cluster_rpc): fail fast on stale state
Due to:

* Cluster RPC MFA is not idempotent!
* There is a lack of rollback for callback's side-effects

For instance, when two nodes try to add a cluster-singleton
concurrently, one of them will have to wait for the table lock
then try to catch-up, then try to apply MFA.
The catch-up will have the singleton created, but the initiated
initiated multicall apply will fail causing the commit to rollback,
but not to 'undo' the singleton creation.
Later, the retries will fail indefinitely.
