Add or remove hostnames for a property's hostname bucket

Beta. For a property with useHostnameBucket set to true at creation, this operation adds or removes up to 1000 property hostnames without incrementing the property version. Changes are automatically activated on the selected network. If a property doesn't have hostname buckets enabled, this operation returns a 403 forbidden error. If another activation is in progress, whether it is a hostname activation or a property version activation, the operation is blocked and returns a 409 Conflict error. Once you perform this operation, it will block subsequent requests until all the property hostnames are active. Note that to build the request body, you must first obtain the edgeHostnameId either from an existing edge hostname or a new one you create by running the Create a new edge hostname operation.
