Enable monitoring and alarms for CMSSW popularity service

[nikmagini]

Hello,

the CMSSW popularity collector running on vocms044 doesn't come back up automatically after a reboot. Suggesting to add:

• automatic restart of the service; could be done using the simplevisor like other popularity services
• monitoring and alarms in case the automatic restart fails; could be done with lemon metrics like other cmsweb services

Cheers
Nicolo'

Automatic restart of the service is now enabled using /opt/dashboard/cron/dashbServices.sh provided by dashboard.
This script requires to run as non-root.
Since the service is currently running as root on vocms044, as a workaround the script has been manually edited commenting out the check on the root user. For a permanent solution, the service should be migrated to run as non-root.
