Gregory Thiemonge 8a47577b76 Fix race condition in members batch update API call ...

Fix a potential race condition, the member batch update API call
computes a delta between the current state of the members in the DB and
the members in the requests. But it fetches the members from the DB
before locking the load balancer, it means that another Octavia service
may still update the list of members, then the computation of the
changes may be incorrect.

The list of members is now queried in the locked section.
