This change allows the embedded ansible process to be configurable by
the end user.
* Python requirements and ansible roles will all now be user
configurable.
* Setup is now a local only playbook. This playbook replaces the bash
commands we were rerunning when the `bootstrap-embedded-ansible.sh`
script was executed.
* Embedded ansible version is now 2.7.5 as default.
* Deprecation warnings have been resolved.
* Tests impacted by this change have been updated.
