[storage-rdma] Make StoragerServer ep active to prevent orphaned CQ

The passive endpoint model caused an orphaned CQ at DataNode
after each client disconnect. Each new client connection caused
creation of another CQ. Changing to an active endpoint model
frees the per client CQ after client disconnect. Since the CQ is
not actually used (the endpoint handles only RDMA Read and
Write from client side), the active endpoint gets created with
minimum resources (send/receive/completion queue size == 1),
and the CQ event dispatcher is a nop.
