repmgrd: improve detection of status change from primary to standby

Browse Source 
If repmgrd is running in degraded mode on a primary which has been stopped,
then manually been brought back online as a standby (e.g. by creating
recovery.conf and starting the server), ensure it not only detects the
change but automatically updates the node record so it can resume
monitoring the node as a standby.

Previously, repmgrd was looping waiting for the record to be updated
(as is done transparently when executing "repmgr node rejoin") but
if the record was not updated within the timeout period (e.g. by
"repmgr standby register) it would fail to resume monitoring as a
standby.

It seems reasonable to have repmgrd automatically update the node record,
as this will restore failover capability as quickly as possible. If this
is not desired, then the onus is on the user to shut down repmgrd while
making the desired changes.
