Deploy a pod serving the git config repo

[chaen]

Our config is stored on gitlab repository, and we have been hitting it too hard.
The cache is being improved but it still is desirable to:

• not have the rate limit
• not depend solely on external source for the config, as it means it can prevent bootstraping if the source is down

The best solution is to deploy a pod which clones the source repo on a persistent storage, and then serve it over http to all the other pods.

This seems like a good alternative to the local git configuration on a shared storage which seemed complicated for many installations
