Add new script to alarm on late workflows

Implement it under bin/ it uses an external
config file to get the limits and support run blacklists
writes the file to: /afs/cern.ch/user/c/cmsprod/www/sls/cmst0_late_workflows.xml
Service name in the XML is CMST0-late-workflows

Also move the backlog alarm to bin/ and add a functional version
of the Config file to etc/operations.

Note that the scripts are now named with underscores instead of dashes, this is to make
it compatible with attributes and module names in Python.
