master_failover-itest: eliminate some flakiness
Due to the inherent asynchronicity of SIGSTOP and the lack of "exactly once"
semantics [1], it's possible for any DDL operation issued by these tests to
return a result suggesting it had already been performed prior to being
issued. See TestCreateTableSync for a detailed example.
I've never run into this myself, but it has occurred at least once [2] in
the wild.
1. EO semantics are being implemented as part of the replay cache work, but
to fix this particular problem we'll need some additional logic (i.e.
we'd need to copy RPC information from e.g. CreateTableRequestPB into the
replicated WriteRequestPB that corresponds to the created table).
2.
