[SERVER] labs deploy a user container

[andreaswachs]

What needs to be done?

To make this PoC interesting, labs should deploy a user container to deployed labs.

There are several options for which kind of container to use:

• Create a kali linux container with a GUI, take inspiration from here
• Deploy a kali linux container without a GUI
• Deploy a linuxserver.io webtop

The networks package needs to be expanded to track ports in use, as we need a port to the container to use some remote desktop software to log into it

resolves #30

Acceptance criteria

• Some container is deployed to labs
• Networks package tracks ports in use by Daaukins and can query for an unused port to use for the user container(s)
