Update octavia-tempest-plugin configref

This patch updates the octavia-tempest-plugin configuration reference
documentation to only include octavia-tempest-plugin specific
configuration options.
This simplifies our documentation and means bugs in other plugins will
not break our configuration reference docs job.

It also re-enables the docs job, disabled in a previous patch.
