Update VPLMN status in network coverage configuration
This will disable/enable the operator contained in the specified `network_coverage_data` object.
The JSON payload should patch the `status` object to have an `id` of `1` (enabled) or `0` (disabled).
The availability status of a VPLMN may be changed at any time.
Changes will be immediately applied, but only for new location update requests.
Subscribers already camping on that VPLMN will not be affected until their next location update.
