As per the discussion in [1] extension specific exceptions that are not API facing would best live outside the api-def itself. This patch suggests added an exceptions package that will allow per-component exception definitions as sub-modules (ex: neutron_lib.exceptions.l3). The existing exceptions from neutron_lib.exceptions.py are defined in neutron_lib.exceptions.__init__ and don't impact existing consumers import them.
