I am in support of this proposal

I have 2 requests to merge this as accepted:

• Let's put this in a separate repo inside cortexproject, where the selected maintainers will be able to keep this component updated.
• We need 2 maintainers for this. (I can't be a maintainer, sorry). I am expecting you will be one of the mantainers. Can you find 1 person to help you with this?

+1 on making sure there are at least 2 maintainers for this provider component.

Support a separate repo within the project.

Why connection and auth only? And how tenant config will be consumed by Cortex?
