[apavanello]

PR ref #103

Add two new lib files (library/dokku_resource_limit.py and library/dokku_resource_reserve.py) and update Readme

thanks a lot for the contribution @apavanello, very welcome!

Please see below a few comments - I noticed too late that I made my suggestions in the README, i.e. you'll need to move them to the source file (sorry).

It would be nice to add a test of this new functionality somewhere here but for this we first need an app installed during the verify stage. Unfortunately, my PR #98 that would do this is blocked by a longstanding molecule bug and there doesn't seem to be any action on it... until that point no need to add a test

Hi,

Maked changes on source to create a correct README and maked a allowed_keys to be agnostic, in fact i don't need check the output of dokku --quiet resource:limit myapp because the output will have only two returns, the full list of resources (even when no have limits/reserves) and the error (when the app doesn't exist), so i use the current output to generate the allowed_keys list, when dokku add new resources no need to change the list

In test subject, i created a branch in my repo and added some tests and all have pass (you can check in my github actions https://github.com/apavanello/ansible-dokku/actions/runs/818794950), when #98 be fixed i can make another PR to implement the resources tests

Sorry for english mistakes,i still learning the language

Cheers, I think I started to get an idea of where the molecule issue comes from. Will ping you once this is done (but we will merge this PR nevertheless).
