In order to allow easier updates from upstream hardware vendors, we're going to be hosting network hardware
config modules on Galaxy as announced during the last release cycle.   (This excludes load balancers, which remain in core).

Closes-bug: #8299

Handle the case where include_pattern and exclude_pattern exist but are empty strings

need to handle the case where include_pattern and exclude_pattern exist in the config file but contain empty strings

Fix issue #8578. Setting envvar in ""'s ensures the PYTHONPATH is set to

include the lib/ directory.

Before - PYTHONPATH is empty.. ansible fails to run

    $ source hacking/env-setup.fish
    Appending PYTHONPATH

    Setting up Ansible to run out of checkout...

    PATH=/Volumes/opt/src/ansible/bin /usr/local/share/python3 /usr/local/bin
    /usr/bin /bin /usr/sbin /sbin /usr/local/bin /opt/X11/bin /usr/bin /sbin
    /usr/local/bin /Users/ms/bin/
    PYTHONPATH=
    ANSIBLE_LIBRARY=/Volumes/opt/src/ansible/library
    ...

    Traceback (most recent call last):
      File "/Volumes/opt/src/ansible/bin/ansible", line 25, in <module>
          from ansible.runner import Runner
          ImportError: No module named ansible.runner

After change - it's set.. ansible runs.

    source hacking/env-setup.fish
    Appending PYTHONPATH

    Setting up Ansible to run out of checkout...

    PATH=/Volumes/opt/src/ansible/bin /usr/local/share/python3 /usr/local/bin

    PYTHONPATH=/Volumes/opt/src/ansible/lib:
    ANSIBLE_LIBRARY=/Volumes/opt/src/ansible/library
    ....

    $ ansible
    Usage: ansible <host-pattern> [options]

ansible-vault should support script for --vault-password-file too
