Update mariadb-server suspect_timeout to default value to align
with garbd's suspect_timeout In openstack-helm-infra, it launch evs.suspect_timeout=PT30S for mariadb-server in configmap, mariadb-etc. This setting is for three mariadb-server pod deployment, every mariadb-server with same setting suspect_timeout=30s. But after change to two mariadb-server and one garbd arbitrator. Setting in configmap mariadb-etc evs.suspect_timeout=PT30S, only takes effect for 2 mariadb-server, for garbd arbitrator, it use galera default setting evs.suspect_timeout=PT5S. If mariadb-server-1 exit abnormal, after 5s, garbd arbitrator suspects mariadb-server-1 is dead, but as not reach 30s, mariadb-server-0 thinks mariadb-server-1 is not dead. In this state, quorum fail, garbd arbitrator and mariadb-server-0 both set to none primary component, service down. For fix solution, set value.conf.data.config_override to override wsrep_provider_option in mariadb helm chart, which makes garbd arbitrator and mariadb-server launch with same setting for "evs.suspect_timeout=PT5S", default value. By this way, mariadb server recovery time will also improve. To update setting for "evs.suspect_timeout", it should both update override for mariadb and garbd helm chart. Setting for "gmcast.listen_addr=tcp://0.0.0.0:<port>", takes effect for both ipv4 and ipv6. So keeps such setting.
