Put all monitors that run on segments* machines into a repo and set up automatic installation

There are several monitors on various segments* machines that have been created on those machines in the past few years but are not under version control (i.e., added to a repo) or installed as part of a new installation. Both of those aspects should be addressed.

Monitors on various machines:

• segments.ligo.org
  • x
• segments-backup.ligo.org
  • x
• segments-web.ligo.org
  • x
• segments-dev.ligo.org
  • x
• segments-dev2.ligo.org
  • x

Some information on various monitors can be found here.
