[octavia] problems configuring octavia

Hi Daniel,

It might be helpful to use the [charms] in the subject as I think
everything you mentioned here is related to the Ubuntu/juju/charms
deployment tooling and not the Octavia project. I don't have any experience
with doing a deployment with charms, so I can't be of much help there.

That said, Octavia does not rely on DNS for any of its operations. This
includes the lb-mgmt-net and for the load balancing elements. So, the lack
of access to BIND for Octavia is not a problem.
