In essence, this configuration option will ensure that a Patroni cluster running with a static primary will not demote the master unnecessarily. Transient failures to update the leader lock in the DCS will not cause a demotion when running with a static primary. When running as leader under normal circumstances, DCS exceptions will not cause a demotion when running with `static_primary=thisNode`. Even if replicas are added to the Patroni cluster, Patroni will be able to protect itself from entering into unsafe states by checking the value of static_primary. If the configured static_primary is not the host node, then the replica will refuse to progress to postmaster boot. If the configuration was dynamic, then the replica will shutdown when such a state is detected. Added behavioral tests for static primary feature.
