RDMA/restrack: Introduce statistic counter

Browse source 
Introduce statistic counter as a new resource. It allows a user to monitor
specific objects (e.g., QPs) by binding to a counter.

In some cases a user counter resource is created with task other then
"current", because its creation is done as part of rdmatool call.
