[rpc] introduce rpc_listened_socket_rx_queue_size metric
This patch introduces a new 'rpc_listened_socket_rx_queue_size'
histogram metric for AcceptorPool. The metric allows for tracking
the size of the listened RPC socket's RX queue. The new metric
shows meaningful numbers only on Linux since it's based on the
DiagnosticSocket, where the latter is implemented only on Linux
as of now.
The new metric is sampled by each acceptor thread when accepting
an RPC connection. It's possible to change the frequency of the
sampling (completely disabling it, if necessary) by tuning the
--rpc_listen_socket_stats_every_log2 flag.
I also added basic tests scenarios to cover the newly introduced
functionality.
