Code Issues Proposed changes

Add support for extra Python packages inside Ansible runtime 

At the moment there is no well defined way to supply list of extra Python
requirements for Ansible venv. However, some collections for their work might
require presence of extra libraries inside the execution environment.

While PIP_OPTS might be used right for that, it's usage is not transparent
or documented.

In order to handle such need, `user-ansible-venv-requirements.txt ` is being implemented
that reside inside OSA_CONFIG_DIR and contains list of required packages
for installation when running bootstrap-ansible.sh

Installing extra Python packages inside Ansible virtualenv
----------------------------------------------------------
Some Ansible collections may require presence of specific Python libraries
inside execution environment.
In order to accomplish that deployer can create ``/etc/openstack_deploy/user-ansible-venv-requirements.txt``
file with a list of Python libraries that should be installed inside virtual
