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/. JIRA: APEX-317 Change-Id: I3232f0329bcd13bce5a28da6a8c9c84d0b048024 Signed-off-by: Tim Rozet <trozet@redhat.com>
