Reduce dependencies on the dest nodes

Currently we require a slew of deps on each destination node, this
includes a gcc compiler and installing things via pip. We can remove
these dependencies by containerizing them and running and Ansible
inside the container itself. The container would then report back
facts about idempotency.

Closes-Bug: #1481495
Implements: blueprint containerize-dependencies
