Multiple improvements to `Apollo`

[BitTheByte]

Summary

A few non-breaking code changes to improve prefect-apollo service

Importance

• Prevent artifact folders from being uploaded to git
• A toggle option for logging as it was affecting performance
• Improved Dockerfile to help developers build faster local images
• Introduced a new deployment using PM2 to take full advantage of the clustering feature allowing more robust and production-ready workloads. keep in mind the command section needs to be removed from helm/prefect-server as it's now integrated within the startup script. if kept as it is, no conflicts will happen.

Checklist

• ~[ ] adds new tests (if appropriate)~

Hi @BitTheByte! Thanks for contributing. This is a lot of changes rolled into one, so let me try to address each one.

Prevent artifact folders from being uploaded to git

:+1:

A toggle option for logging as it was affecting performance

This change appears to only disable startup logs. I can't see this affecting general performance but I am amenable to it. It seems safe and reasonable enough

Improved Dockerfile to help developers build faster local images

I have left some feedback there for further improvement in my review, but it is a straightforward improvement

PM2

This change is a bit heavier. Server is not built to support running multiple processes today and this particular change may be too risky/ test-time-intensive. I think this should be relatively achievable as a layer on top of Server in your particular implementation without having to maintain it here
