1. Start OVS components in containers so that building and shipping
    of OVS components is easy.
 2. Load OVS kernel modules on host from container to avoid installing ovs
    on host.
 3. Update documentation about how to build/run ovs in docker.

As discussed in the meeting today,  can you please provide the option to
enable or disable kernel module compilation
when building the docker images in a follow up patch.

Also, is it Ok if your signed-off-by email id is different from the Author
email id ?

Thanks

It's better if they're the same, otherwise it gets confusing.
