'master' branch in this repo doesn't match 'master' in KEDA repo

[eashi]

The master branch in this repo is synchronized with the KEDA container tagged by latest, which is NOT the master in KEDA repo.

This adds confusion if there is a breaking change in master KEDA, just like the fix #347 for resolving the host from environment.

Should master of this repo synchronise with master in KEDA? Or maybe put a statement at the beginning of README.md that you should check branch x if you are using a KEDA that was built from master.

I feel the release story can be a little better?

Yep makes sense - some awkwardness for this sample specifically as was impacted by a breaking change before we moved KEDA to 1.0 and started using explicit version tags. That has been cleared up and we have a better release process now. Let me know if any other pending items here.
