Add automatic dependency bumps

[mnaser]

We've got a few things that need to be updated automatically:

• [ ] Packages for infrastructure services (Ceph, containers, Kuberentes)
• [x] Images for services
• [ ] Versions for charts

We should probably use renovate to take care of this since I think we're going to be limited in our options with dependabot

https://github.com/vexxhost/atmosphere/pull/391 addresses the image bumps which can be done manually now.
