0 exit code for cases of failed activation

If there is a pending activation cloudlets CLI is returning 0 instead of 1.

I do think that problem is in missing exit(-1) after https://github.com/akamai/cli-cloudlets/blob/aafb134754fee56e955a87720e56f7947d69d6ab/bin/akamai-cloudlets.py#L641

I would expect to have 1 exit code
