Why/How I did:
Make sure first error syslog is triggered based on FAULT TOLERANCE condition.
Added support of repeat clause with alert action. This is used as trigger
for generation of periodic syslog error messages if error is persistent
Updated the monit conf files with repeat every x cycles for the alert action
The psutil library used in process_checker create a cache for each
process when calling process_iter. So, there is some possibility that
one process exists when calling process_iter, but not exists when
calling cmdline, which will raise a NoSuchProcess exception. This commit
fix the issue.

- monit config broke by one monit upgrade
- abandon sed approach since it is suspestible to monit config changes
