Dead code and model remain for availability ranges

[Carl Baldwin]

Availability range models and code are effectively obsolete [1] and should've been removed
in a previous patch [2] but some of it was left behind.

Fix: https://review.openstack.org/#/c/349709/

It is almost all code removal with a migration that simply drops the two tables (one for pluggable and one for non-pluggable IPAM).

Does the bot not link the patch in progress anymore?
