UML-2912 Get local https working.

[cooperaj]

Purpose

Fix https running for local dev. At the moment we have certificate problems due to lack of local https running. In Make an extra container is run to take care of this, however that may have downsides. This story is to find a simple solution that works for everyone.

Fixes UML-2912

Approach

Using a Traefik proxy container to proxy existing ports to the services with the addition of self-signed HTTPS ports being made available and redirected to as we currently do at the AWS LB level.

Seems to work well for me 🎉

Might be worth changing the default protocol/port in the readme to push people onto HTTPS, though the redirect's great
