Adds configurable hosts for hamilton ui

[skrawcz]

Settings mini is used by default by the Hamilton UI command. This changes it to enable changing
ALLOWED_HOSTS by passing in some environment variables.

It then automatically adds a few of them, like the current IP, etc.

Changes

• settings_mini.py

How I tested this

• locally
