Improvements to config file updates

1) Some text editors will create a new file and move it into place
on top of the existing file. When this happens, the kernel issues
an IN_IGNORE inotify event and automatically removes the watch
descriptor for that file. We'll handle the event and create a new
watch descriptor for the new file. We will attempt to rewatch the
file six times at five-second intervals.

2) Some scripts may append new data to the config file in several
steps (such as calling echo "foo" >> sssd.conf several times). In
order to handle these scripts safely, we'll defer processing of
inotify events for one second after the first is detected. This
should be ample time for the remainder of the script to complete.
