Fixes mode argument with --mode=genanswers

When `sudo atomic run projectatomic/helloapache --mode=genanswers` is
supplied, the resulting error shows that `--mode=genanswers` is an
unrecognized argument.

This was introduced after refactoring the cli/main.py code to NOT include
uneeded parameters such as --provider-auth to CLI options such as init
and genanswers.

By moving the --mode parser to the globals_parser, each command will
have the --mode option available.

Fixes #792
