CLI needs a -f flag

Particularly in the removal commands I would like to specify a -f and tell it to take the most destructive action it can regardless of errors.

So for instance if the namespace of an app had been deleted from up under deis I would like to say deis destroy -a myapp -f and it not error but remove everything about that app it can regardless of the errors returned.

Copied from original issue: deis/workflow-cli#258

This needs to be also implemented in the API and I don't think we will do varying levels of removal etc - instead we should just fix the controller ticket you opened up

@helgi This could actually be all client side and replace the --confirm=<name> syntax we currently use for forcing.
