Update the limits of a QoS definition
You can use this call to update either only the Downlink, Uplink or both pam_limits
The following fields can be specified in the request body:
- `max_bandwidth_dl`: an unsigned int32 specifying the maximum allowed bandwidth on the downlink in bits per second
- `max_bandwidth_ul`: an unsigned int32 specifying the maximum allowed bandwidth on the uplink in bits per second
Note that you cannot limit all rat_types, just those that are limitable.
Use `GET /api/v1/rat_type?limitable` to retrieve them.
