Log warning if "standby_disconnect_on_failover" used on pre-9.5

Browse Source 
"standby_disconnect_on_failover" requires availability of "wal_retrieve_retry_interval",
which is available from PostgreSQL 9.5.

9.4 will fall out of community support this year, so it doesn't seem
productive at this point to do anything more than put the onus on the user
to read the documentation and heed any warning messages in the logs.
