Ian Barwick 38e3aae053 repmgr: add parameter "shutdown_check_timeout" ...

Previously, "repmgr standby switchover" used the configuration file parameters
"reconnect_interval" and "reconnect_attempts" to define a timeout to determine
whether the current primary (demotion candidate) has shut down.

However, these parameters are intended for primary failure detection and are
generally lower in value, while a controlled shutdown may take longer, resulting
in the switchover being aborted as repmgr was not waiting long enough.

To prevent this happening, parameter "shutdown_check_timeout" has been added.
This complements the existing "standby_reconnect_timeout" parameter used
by "repmgr standby switchover".

Implements GitHub #504.
