Adrian Chiris f4f591aee8 Add support for getting all RDMA devices in the system
- Add RdmaLinkList() method that retrieves RDMA devices
  in the system.

- Modify RdmaLinkByName() to use RdmaLinkList() to avoid code
  duplication.

- Add unit test that demonstrates how to use RdmaLinkList()

Parav Pandit 4666477197 Add an API to query RDMA subsystem net namespace mode
RDMA subsystem can be running in shared or exclusive mode with regards
to sharing RDMA device sharing among multiple network namespaces.

Add and API to query such mode of kernel similar to iproute2 command
$ rdma system show netns

Parav Pandit 1970aef3ab Add RDMA netlink socket for RDMA device information
This patch adds very basic support for getting information about RDMA
networking device; starting with device index, name, firmware version,
node GUID and system image GUID.
This is done through RDMA netlink socket.

RDMA devices are some what similar to Ethernet devices.
However there are few major differences between them.
RDMA devices usually have one or two ports, unlike Ethernet devices.
Each port has its own attributes, state and network addresses which are
different than Ethernet devices (Link and LinkAttrs). They almost don't
overlap with Link and LinkAttrs.

Therefore it doesn't derive Link and LinkAttrs structure; instead they
are represented using RdmaLink and RdmaLinkAttrs.

RdmaLink represents a RDMA device containing its attributes.
All Rdma device communication occurs through rdma subsystem's netlink
socket.
