When using OVS, sockets are not created in correct dir about userspace-cni-network-plugin

[kangasta]

I have edited the ovs_config.py script so that the socket file is moved to /var/lib/cni/vhostuser/$CONTAINER_ID/ and after this I can use the socket from inside the container similarly that I expect would be the process when using VPP.

From what I have understood, when using VPP as the switch the vpp_config.py creates the sockets to /var/lib/cni/vhostuser/$CONTAINER_ID/ and these are taken into use from inside the container by mounting the .../vhostuser/ folder and by using the get-prefix.sh script to get the container ID. Have I understood this correctly?

@kangasta Can you send me the PR, I will check the changes and merge it?

@kangasta /var/lib/cni/vhostuser/$CONTAINER_ID/ is for the saving the rendered netconf for cmdDel and application.

If you wish for the vhost-user sockets to be created in a sub-directory of /usr/local/var/run/openvswitch, you may specify this directory in the ovsdb like so:

$ ovs-vsctl --no-wait \
    set Open_vSwitch . other_config:vhost-sock-dir=subdir

Agree that I should update the README for the OVS separately :)

Yes, you are correct on this.
