Add postgres helm chart as dependency

[chainlink]

Description

This adds the bitnami postgres chart to Lumigator. It vendors (commits) the subchart for easy install (no helm dep required)

This installs postgres by default when installing via helm for kubernetes.

This does not allow for passing in an existing postgres installation, that option will be added in a future PR.

Other cleanup:

This cleans up old postgres vars present in the code but unused

To test

helm install lumigator lumigator --set image.tag=backend_dev_ -f cw-values.yaml

cw-values.yaml

global:
  storageClass: shared-vast # For Postgresql

There's the annoying issue about the huge_pages=off setting in some deployments :-/ Is it worth it to add the details to some of the readme files?

Can you elaborate?

Can you elaborate?

There's some info on this issue here: bitnami/charts#7901
I'd assume any usual cloud provider would provide hosts with huge pages support out of the box, if you didn't hit this issue.
