feat(#174): bastion Dockerfile and compose file

[mrjones-plip]

Description

This PR:

• Adds new Dockerfile to build a bastion container - based on Alpine 3.20
• adds compose file docker-compose.bastion.yml to define a bastion host to allow SSH tunnels to access postgres
• locks down postgres by removing the ports: lines from docker file so it doesn't expose the port externally (unless you run pgadmin compose file)
• splits off pgadmin into it's own compose file. most of the time this shouldn't be run alongside postgres because it exposes a publicly accessible HTTP port that with no password set. While you do need to know the POSTGRES_PASSWORD, I think this is still to "insecure by default" so we should silo them off by default instead
• adds ports: file to pgadmin compose file for postgres server
• defaults all e2e tests to go through bastion host, just as it will in production

closes #174

@witash and @njuguna-n - is it OK to remove these two lines that expose the postgres ports ? for a sane default for production I don't think we want this exposed - I've removed it in this PR.

Related: For development I think we should use pgadmin. I also think we should break out pgadmin to it's own docker file so it's not run by default in production. - I went ahead and did this while I was in there!

Thought: Instead of docker-compose.pgadmin.yml, we could call this docker-compose.developer-postgres.yml or something. It would not only add pgadmin service but also expose 5432 for postgres server defined in docker-compose.postgres.yml. This is nice b/c you can easily run it in development and it's clear what it's point is. I think most production instances should not expose pgadmin on 5050 by default - but maybe I'm taking it too far?

services:
  postgres:
    ports:
      - 5432:5432

  pgadmin:
    image: dpage/pgadmin4
    environment:
      PGADMIN_DEFAULT_EMAIL: ${PGADMIN_DEFAULT_EMAIL:-pgadmin4@pgadmin.org}
      PGADMIN_DEFAULT_PASSWORD: ${PGADMIN_DEFAULT_PASSWORD:-admin}
      PGADMIN_CONFIG_SERVER_MODE: 'False'
    ports:
      - "${PGADMIN_PORT:-5050}:80"

@njuguna-n or @witash - before I send this PR out for formal review - can you point me toward how I should add tests for the new bastion container? Maybe an existing pattern we have? I'm a test n00b and need a little guidance :pray:

thanks!

Hello @mrjones-plip for this one you are looking at adding e2e tests right? You can have a look at existing e2e tests here for some guidance.

[mrjones-plip]

While ready for review, I think we should wait until #187 is merged. Then I can get all a green CI on this branch - otherwise right now green CI is impossible because of #186

@lorerod and @dianabarsan - if you can't wait, you can have a preliminary look at e2d and new bastion container respectively! Otherwise, feel free to wait until this PR is fully baked.

Maybe I'm not being patient enough? !
