Make arches-containers an installable python module and implement a CLI

[aj-he]

Currently the solution needs to be cloned and then manually triggered in a particular order.

Creating an installable CLI for creating and managing these configurations will allow users to automate workflows for setting up a developer environment.

It would also be great to be able to export a configuration so that it can remain with the Arches project repo.

It should allow the user to save arches repo configuration and organisations so forks can be supported.

The user can have multiple ac projects in the workspace to allow multiple configurations. Users can have an active project to shorten commands.
