When containers are connected to a OVS bridge and tunnels
are created, it makese sense to reduce the MTU of the interafce.

For testing OVN, it is useful to set the mac address
of the container. Since ovs-docker hasn't been part
of any released versions of OVS, it is probably OK
to change the options style.

Reuse code for determining attached port to prevent ovs-docker to proceed if a
port for the given container and interface is already attached.

Currently, the script uses '--version' option from different commands
to check for their availability. uuidgen on Centos6 has been reported
not to have the '--version' option causing failure in script invocation.
This commit looks for the utilities in $PATH instead. The code is
copied from build-aux/dist-docs.

For containers containing multiple ports and spawned by
orchestrators without openflow flows configured, it can be quite
useful to distinguish their traffic with vlans. This can be useful
when containers are spawned inside VMs instead of hypervisors.

ovs-docker currently lets one add the ability to set the
IP address on an OVS interface. Ability to set the default
gateway too can be an useful addition. (orchestrators
who plan to use OVS interfaces can do this from a single
utility instead of multiple utilities)

Open vSwitch does not have native integration with Docker.
INSTALL.Docker explains how Open vSwitch can be integrated
with docker non-natively.
ovs-docker is a helper script to add network interfaces to
docker containers and to attach them as ports to OVS bridge.
This script can be further enhanced as we understand different
use cases.
