[PATCH iproute2-next 3/4] rdma: Add support to get CQ in raw format

[Leon Romanovsky]

From: Maor Gottlieb <ma...@mellanox.com>

Add the required support to print CQ data in raw format.
Example:

$rdma res show cq dev mlx5_2 cqn 1 -r -j
[{"ifindex":8,"ifname":"mlx5_2","cqn":1,"cqe":1023,"users":4,
"poll-ctx":"UNBOUND_WORKQUEUE","adaptive-moderation":"on",
"comm":"ib_core", "data":[0,4,255,254,0,0,0,0,0,0,0,0,16,28,...]}]
