Mariadb: define timeouts for wsrep

Browse Source 
This PS updates the wsrep_provider_options to define the timeouts
explitlcitly for evs.suspect_timeout, gmcast.peer_timeout. Their
defaults are PT5S, and PT3S respectively, which are increased by
a factor of approx 5, to accomdate network instability that may
occur during node outage events.
