Adding retry clause in the event that docker inspect is called too quickly
Virtual LAN (VLAN) support for Open vSwitch and physical interfaces

If you want to attach the container to a specific VLAN, the VLAN ID can be
specified using the `[MAC]@VID` notation in the MAC address parameter.

**Note:** VLAN attachment is currently only supported for containers to be
attached to either an Open vSwitch bridge or a physical interface. Linux
bridges are currently not supported.

The following will attach container zerorpcworker to the Open vSwitch bridge
ovs0 and attach the container to VLAN ID 10.

    pipework ovsbr0 $(docker run -d zerorpcworker) dhcp @10
