Add missing quota flags in the config file sample

l3 extensions don't set quota flags in the config sample file
etc/neutron.conf.
Quota is unlimited if its value is minus and not only if it's -1.

nicira: fix db integrity error during port deletion

Due to the fact that plugin port operations are not
transactional (as they involve non synchronized DB
and Controller operations), concurrent (interleaved)
port requests may accidentally cause the insertion
of the mapping entry (neutron-port-id, nvp-port-id)
more than once. In case this occurs, it's safe to
expect the failure and continue the normal process
of the operation being requested.

Fix empty network deletion in db_base_plugin for postgresql

Need to disable joined loads for port query in delete_network
as in other methods.

No unit test is being added, because the problem is not reproducible with
sqlite.
