There are other bits of the nova-network code which assume bridge # maps
to vlan #, so I'm not sure this is reasonably changable above the driver
layer. I suspect a warning that vlan and bridge are incompatibile
options in the client would be the near term fix.

Title:
  nova network-create is ignoring --bridge when using the VlanManager

Status in OpenStack Compute (Nova):
  Incomplete
Status in Python client library for Nova:
  Confirmed

Bug description:
  The `nova network-create` is *silently* ignoring the --bridge when
  using the VlanManager. The bridge name is hardcoded to "br%s" % vlan.

  It would be good to have the bridge name configurable when using
  VlanManager because when the nova vcenter driver is used, nova is
  checking whether there is a "port group" in the vcenter of same name
  as bridge used in nova-network.
