included add config and show config features

[babarinde]

Hi @pst,
Add config and Show Config features added
One issue with implementing the remove config was, passing the variables seem to be a challenge.

In https://github.com/cloudControl/cctrl/blob/master/cctrl/app.py#L740 ,
args.variables expects to be an array (i think) as defined in
https://github.com/cloudControl/cctrl/blob/5fcdca83fc6fb26676b1ff3aa4f241663aa400de/cctrl/addonoptionhelpers.py#L69
getting an array of the keys to the delete http request is quite a challenge.
This is my first encounter with python so i guess my assumptions are quite right.
Cheers

Thank you for the pull request. I think the added functionality is fine.
Changing the indentation from spaces to tabs, and leaving it in a mixed state is not so beneficial. If you can correct this, I'm happy to merge it.

Hi @TooAngel,
I sorry i haven't been able to do the formatting, however i also have a more pressing issue as regards the pull request now.
It seems the api.cloudcontrolled.com does not implement the resource that i speculated for adding config variables

/app/APP_NAME/deployment/DEPLOYMENT/config/

as when i try to add some config variables i get this error

no valid json: Gone Method 'POST' not allowed.

I also try changing the request to a PUT but i get the same error
Could it be that i am using the wrong resource?
Thanks and looking forward to your response.
