This commit adds an initial support for rdmacg of linux, that enables
controlling rdma related resources (currently HCA handles and HCA
objects).

This is a very early stage PR. I'm really glad if I can hear opinions about the idea of managing RDMA related resources from runc.

You'd want to submit a corresponding PR to opencontainers/runtime-spec as well as doing this -- because ultimately the runc configuration is sourced from an OCI configuration. We don't merge spec-level changes into runc unless there's been a spec change in runtime-spec (though overall rdma shouldn't be too hard to implement overall).

@cyphar thanks for your comment. I'll create a PR for the spec side later.

I'm closing this because @paravmellanox has the good reference implementation.
