rumba: Remove irati/rlite, python2 and qemu support

Remove IRATI and rlite prototype plugins, keeping only Ouroboros.
Delete .gitlab-ci.yml (only contained an irati test job and a
Sphinx pages job). Clean up all irati/rlite imports and references
from examples, documentation, and tools.

Qemu was tied heavily with rlite and irati. As it's less useful for
ouroboros it's removed rather than reworked.
