Register Component into Software Catalog and setup TechDocs publishing

This PR adds the necessary files to the repo to:

• enable Grafana Backstage to catalog this service
• set up TechDocs site and publishing

You will still need to tag the repo with the appropriate topics to make it show up in the catalog.
Please see this link for instructions on how to tag your repo.
