Badger release process

Correction, the dgraph-maintenance branch isn’t stable. I have cut the branch from the badger commit dgraph master has currently. I could’ve cut a branch from a previous stable point but then we’d be losing the memory/performance optimizations (which have bugs). If we’re okay with losing optimizations and some fixes, let’s use the badger v2.0.3 which was released in March 2020, that’s the last released badger version and it’s stable.

For 20.03.4 are we comfortable with this branch or do we need to go back to the changes that were published in 20.03.1 that is recommended to our customers? Dgraph v20.03.1 release

I am assuming March 2020 cut off would be missing some of the changes that were already in 20.03.1
