Tasks hook for preparing BM host for deploying containerized services
This implements a host_prep_tasks hook where we can specify Ansible tasks to perform on the host before deploying containerized services. The hook runs in a single step, the assumption is that we will mostly use the hook for creating per-service directories on the host to ensure we are able to mount them into the containers. (We cannot do this operation via Puppet because all containerized services run their Puppet within a config container, so Puppet doesn't have access to host's filesystem.)
