Migrates Apex to Python

Removes all bash libraries and converts almost all of the code to a
mixture of Python and Ansible.  utils.sh and clean.sh still exist.
clean.sh will be migrated fully to clean.py in another patch.

The Apex Python package is now built into the opnfv-apex-common RPM.  To
install locally do 'pip3 install .'.  To deploy:

opnfv-deploy -d <file> -n <file> --image-dir /root/apex/.build  -v --debug

Non-python files (THT yaml, settings files, ansible playbooks) are all
installed into /usr/share/opnfv-apex/.  The RPM will copy settings files
into /etc/opnfv-apex/.
