./hack/sample configurations not working

[darkmane]

Created an image based off of the tip of master and deployed.

Attempted to use PostGre/Celery configuration and MySQL/Celery configuration from the ./hack/sample directories. And the scheduler never successfully started.

Scheduler log showed that it was getting access denied using the account.
Connected to DB and set the password to the value stored in the webui secret and the scheduler started normally.

Verified and it works. I followed the instructions in quickstart guide which i updated as well.
