[WIP] [PoC] Replace Embedded Ansible with ansible-runner based solution

[Fryguy]

This PR is a PoC of replacing the AWX/Tower based Embedded Ansible with ansible-runner.

What this PR covers:

• Removal of a lot of the ansible tower/awx based code
• Basic seeding of the EmbeddedAnsible "provider" as well as a default machine credential
• Basic git repository CRUD
• Creation and deployment of a service via the service catalog
• Visualizing the terminal output of a run

What this PR does not cover:

• Advanced seeding
• Credential management
• Advanced git repository stuff
  • checkboxes such as Update on Launch
  • federated git management and honoring the git_owner role
• Some settings in the service, such as logging, verbosity
• UI raw_output uses a temporary miq_task that is later deleted by the UI, which should be removed.
• Using the embedded_ansible or perhaps automate role
• Upgrades
• Automate methods that are playbooks directly (without the service/service catalog)
• Tests

See ManageIQ/manageiq-design#45 for a deep dive, and details about the implementation.
