replace gen_server:cast with gen_server2:cast in rabbit_limiter

The limiter is co-located with channels but interacts with queues
which may be on different nodes. It is therefore subject to the
message reordering problem of cross-node gen_server:cast - see bug
19749.

For consistency I replaced gen_server:call as well, though I left the
gen_server:start_link alone in order to avoid the (admittedly small)
penalty introduced by gen_server2's modified main loop.
