Local containerized testing for development

[remingtonc]

Testing appears to have long args, arbitrary system packages, or moving parts per docs: https://stalw.art/docs/development/test
Making a change and running tests thus has friction from an outside perspective.

Example to containerize and codify: https://github.com/stalwartlabs/stalwart/compare/main...remingtonc:stalwart:test-containerize?expand=1

Tests being difficult to run make changes difficult to validate.
e.g. I am trying to add the domain principal to config file provisioning i.e.

[directory."memory"]
type = "memory"
principals = [
  { name = "localhost", class = "domain", description = "localhost" },
  { name = "remington", class = "individual", secret = "asdf", email = ["remington@localhost"] },
  { name = "external", class = "individual", secret = "asdf", email = ["external@localhost"] },
  { name = "president", class = "individual", secret = "asdf", email = ["president@localhost"] },
]

Notably not sure if this is actually needed, but seemed like it was missing compared to usual individual user provisioning flows.

This has been already implemented in the 0.16 dev branch.

Great, I'll look for docs.
