helm-charts Automatically configure Postgres and MySQL databases on startup.

What was changed

Automatically create databases and apply the schemas to them for Postgres and MySQL.

Why?

In order to be able to create new environments via Terraform without having to manually create the databases between the provisioning of the cluster and the deployment of the helm chart.

Checklist

How was this tested:

I used this to provision a Postgres cluster, but no other testing has been done. In particular, MySQL hasn't been tested at all.

Any docs updates needed?

Probably? I'm just giving this back to hopefully help other people, but I don't have the time to do any more work on it myself.
