RDMA/mlx5: Track DCT, DCI and REG_UMR QPs as diver_detail resources. 



Allow user to see driver-specific QPs (the "driver_detail" QPs)
through the rdmatool, when requested.

When creating DCT, DCI and REG_UMR QPs, we designate them as driver_detail
resources.

When filling the QP info for the rdma tool, for the driver_detail QPs:
-the QP type is IB_QPT_DRIVER
-the subtype is a string with the QP name ("DCT", "DCI", "REG_UMR")
