Parallel slave failed to retry in retry_event_group() with error
WSREP: Parallel slave worker failed at wsrep_before_command() hook
Fix wsrep transaction cleanup/restart in retry_event_group() to properly
clean up previous transaction by calling wsrep_after_statement().
Also move call to reset error after call to wsrep_after_statement()
to make sure that it remains effective.
Add a MTR test galera_as_slave_parallel_retry to reproduce the error
when the fix is not present.
Other issues which were detected when testing with sysbench:
Check if parallel slave is killed for retry before waiting for prior
commits in THD::wsrep_parallel_slave_wait_for_prior_commit(). This
is required with slave-parallel-mode=optimistic to avoid deadlock
when a slave later in commit order manages to reach prepare phase
before a lock conflict is detected.
Suppress wsrep applier specific warning for slave threads.
