Subject: 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.

Updated README.md and AUTHORS
