Deprecate running Kuryr-Kubernetes with lbaasv2

This commit marks the deprecation of the support of neutron-lbaasv2 in
Kuryr-Kubernetes. It adds a deprecation message, release note and
removes the usage of lbaasv2 in the upstream gates.

From now on, the default option for lbaasv2 will always be octavia.
