This set of metrics describes how many requests of each type has been processed with outcome specified.
All metrics except for upf_pfcp_rx_latency are counters and labeled with result indicating if message was successfuly processed or rejected.
Note: upf_pfcp_rx and upf_pfcp_rx_errors have different implementation and counted at different points, we will drop one or another after evaluation, or implement a different counters altogether.
