Optimize 'floating_ip_bulk_create' function

The existing floating_ip_bulk_create() DB API method used a for loop and
a session flush operation for each IP created. This patch consolidates
those many operations into a single INSERT statement, which will
perform better than multiple round-trips to the SQL database. We further
optimize the function by making a return of the changed rows optional.
