rdma: Add rdma statistic counter per-port auto mode support 

With per-QP statistic counter support, a user is allowed to monitor
specific QPs categories, which are bound to/unbound from counters
dynamically allocated/deallocated.

In per-port "auto" mode, QPs are bound to counters automatically
according to common criteria. For example a per "type"(qp type)
scheme, where in each process all QPs have same qp type are bind
automatically to a single counter.
Currently only "type" (qp type) is supported. Examples:

$ rdma statistic qp set link mlx5_2/1 auto type on
$ rdma statistic qp set link mlx5_2/1 auto off
