Add pg_ls_archive_statusdir function

Browse Source 
This function lists the contents of the WAL archive status directory,
and is intended to be used by monitoring tools.  Unlike pg_ls_dir(),
access to it can be granted to non-superusers so that those monitoring
tools can observe the principle of least privilege.  Access is also
given by default to members of pg_monitor.
