From: Raed Salem <raeds@mellanox.com>

A counters object could be attached to flow on creation
by providing the counter specification action.

General counters description which count packets and bytes are
introduced, downstream patches from this series will use them
as part of flow counters binding.

In addition, increase number of flow specifications supported
layers to 10 upon adding count specification and for the
previously added drop specification.
