rdma: Add an option to display driver-specific QPs in the rdma tool

Browse Source 
Utilize the -dd flag (driver-specific details) in the rdmatool
to view driver-specific QPs which are not exposed yet.

The following examples show mlx5 UMR QP which is visible now:

$ rdma resource show qp link ibp8s0f1
link ibp8s0f1/1 lqpn 360 type UD state RTS sq-psn 0 comm [mlx5_ib]
link ibp8s0f1/1 lqpn 0 type SMI state RTS sq-psn 0 comm [ib_core]
link ibp8s0f1/1 lqpn 1 type GSI state RTS sq-psn 0 comm [ib_core]

$ rdma resource show qp link ibp8s0f1 -dd
link ibp8s0f1/1 lqpn 360 type UD state RTS sq-psn 0 comm [mlx5_ib]
link ibp8s0f1/1 lqpn 465 type DRIVER subtype REG_UMR state RTS sq-psn 0 comm [mlx5_ib]
link ibp8s0f1/1 lqpn 0 type SMI state RTS sq-psn 0 comm [ib_core]
link ibp8s0f1/1 lqpn 1 type GSI state RTS sq-psn 0 comm [ib_core]
