Shoveler installation and monitoring

Shoveler is simple to install and is currently running a test version on cms-rucio-services.gridpp.rl.ac.uk as set up by Katy. Now it is time to bring into production where it will be installed and managed as a full production service.

When testing first started, I was asked to have a VM created to run Shoveler eventually in production…this was 2 years ago. In case this machine still exists, here is the name:

This was created by Rob Harper in May 2022. It has an inventory personality.
