Add CFGOV Helm Charts for Local Deployment to K8s

[cooldragontattoo]

This PR adds a CFGOV Helm chart that allow for deployment to a local K8s cluster.

Additions

• A CFGOV Helm Chart that includes:
  • 2 init containers:
    • A Busybox container to ensure that the Postgresql and Opensearch Services are running
    • A data migration container that loads test data into the Postgresql Service and indexes that data to the Opensearch service.
  • 2 containers:
    • The CFGOV application (running on PORT 8000)
    • The Apache server that proxies to to that web application (running on PORT 80)
• Adds index.sh and test.sql.gz to the CFGOV docker image.
• A helm deployment guide to the master docs
• A helm-init.sh script to deploy the helm chart effortlessly.
• A helm-uninstall.sh script that tears down everything related to the CFGOV Helm deployment.
• A Helm notes script that outputs instructions for accessing the CFGOV deployment when deployed locally.

How to test this PR

1. Make sure you have a local K8s cluster running.

As a question about best-practices, should the helm/charts/postgresql-16.2.3.tgz and helm/charts/opensearch-1.31.3.tgz files be committed to the repo?

[cooldragontattoo]

@willbarton, I made your changes. @chosak, do you also want to review?

[willbarton]

We need to get the tests running and passing, and it looks like they're failing on OpenSearch.

[willbarton]

It looks like this setting is causing a problem running the unit tests and functional tests in GHA.

I think we'll need to add a OPENSEARCH_DSL["default"]["use_ssl"] = False override to cfgov/settings/test.py for unit tests to work.

For the functional tests... the GitHub Action just calls manage.py runserver, which defaults to cfgov/settings/local.py, which... I don't think it is right. But changing that is out of scope here, so we'd need to add the same override to that file as well.

Alternatively, find a different way to solve the problem running in Kubernetes that this setting fixes.

[cooldragontattoo]

I disabled use_ssl in both local.py and and test.py. Appears that both tests are passing now.

[chosak]

@cooldragontattoo yes, please, I'd still like to review.
