knm_rename_carrier
The 2600Hz number manager rename_carrier module can be used to change a number’s carrier module.
Only admins can use this feature, otherwise an exception is thrown.
It is a “one time” feature in the sense that once renaming is done, the feature is removed from the number’s document.
The value for the "carrier_name" field is a carrier name without the KNM prefix.
Examples:
"bandwidth2""telnyx""local"
Inputs that do not map to a KNM carrier module will fail the request with invalid.
Enabling the feature
Admins that want to be able to use this feature should add "carrier_name"
to the list of allowed features for the system, their reseller account, a sub account or even a specific number.
For example:
    "features": {
        "allow": [
            "carrier_name",
            "cnam",
            "e911"
        ]
