[Feature Request] Instructions for bare-metal/LXC/VM installation without Docker

[valantur]

Is your feature request related to a problem? Please describe.
No

Describe the solution you'd like
It would be great to have instructions on how to install CWA without Docker.

Describe alternatives you've considered
Clonning the project and running the python app from an LXC container w/o Docker.

Additional context
I believe a lot of people who for whatever reason can't or don't want to run Docker would appreciate having an alternative way to run this. I'll try to do it myself in the next couple of days by reading the dockerfile, but some people don't know how to do this and would find it easier to follow step-by-step instructions.
