Prevent Bridge Domain operations on BD 0.
The default bridge domain, 0, is created automatically with static features. It should be modified by neither the CLI nor the API. So add tests for, and reject any operation on BD 0. The new API error message BD_NOT_MODIFIABLE is returned in such cases. Change-Id: Iaf3dd80c4f43cf41689ca55756a0a3525420cd12 Signed-off-by: Jon Loeliger <jdl@netgate.com>
