Adds translation jobs to octavia

With the merger of neutron-lbaas into the octavia project, we need
to enable translation on the octavia project.
This patch updates the octavia project to have the translation jobs
and translate option.

This patch also updates the octavia project description to reflect
it's new role in OpenStack.
