@kenyon Hello it's been a while but i wanted to propose this first draft of the changes i added.
If you have questions or proposals feel free to add them.

The new code looks fine, but looks like we need to get the tests passing.

[Joris29]

@kenyon Added unit tests and improved some old test also changed the cli class itself a bit but still having issues with ubuntu repo gpg check

@kenyon I Updated some things and had to remove CentOS 7 from unit tests as jq is not available by default.
Updated refs and readme i also created clean separate commits so those can added as is i think.
This only supports project config itself not project resources (yet). I will this i a follow up PR but i don't want to make it to big.
