Pau Espin 5fa8f781c3 ggsn: Fix TC_gy_charging_volume_quota_threshold expectations 
in Diameter, the CC-Input/Output direction is defined as follows in
RFC4006:
"""
8.24.  CC-Input-Octets AVP

The CC-Input-Octets AVP (AVP Code 412) is of type Unsigned64 and
contains the number of requested, granted, or used octets that can
be/have been received from the end user.

8.25.  CC-Output-Octets AVP

The CC-Output-Octets AVP (AVP Code 414) is of type Unsigned64 and
contains the number of requested, granted, or used octets that can
be/have been sent to the end user.
"""

So:
* 3GPP uplink is from end user to PGW, and hence 'CC-Input-Octets'
* 3GPP downlink is to end user to PGW, and hence 'CC-Output-Octets'

This test started failing a few days ago since a bug was recently
fixed in open5gs which was swapping the counters in open5gs-upfd:
