This commit contains the initial set of changes to add CNI sevice to libnetwork drivers. This is done using a cniserver which acts as a side car for libnetwork daemon to process CNI requests. Signed-off-by: Abhinandan Prativadi <[email protected]>
* Support HostAccess overlay option * Make HostMode configurable via overlay driver label * Disble SD and start in host-mode by default for CNI dnet * Moving the default dnet port from 2385 to 2389 * Fix hostAccess iptables rules * Implement JoinInfo and LeaveInfo interfaces on all builtin drivers * Enhance JoinInfo and LeaveInfo to allow ip allocation for gateway-ip * Make use of the RequestAddress feature for hostAccess overlay network * HostAccess network must also handle traffic from bridge to ! bridge. This is required for the ingress cases Signed-off-by: Madhu Venugopal <[email protected]>

I think this needs to be statically built since you don't control the environment it will end up running in -- it is run in the context of the runtime (so maybe cri or docker, perhaps in a container) and not in a container/env supplied by libnetwork.
