Change subject: add aggregated rtp connection stats to osmo-mgw
......................................................................
add aggregated rtp connection stats to osmo-mgw
Add a counter group for aggregated RTP connection statistics.
This group contains RTP counters which aggregate values of the
ephemeral RTP counters maintained per connection (mgcp_conn).
This provides a global overview of RTP processing for each
trunk throughout the lifetime of the osmo-mgw process.
The counters are displayed by 'show mgcp stats' and 'show rate-counters'.
