Enable adoption of an existing subnet into a subnetpool

Registered by Armando Migliaccio on 2016-04-01

It is currently not possible to take an existing subnet and move it into a subnetpool or address scope. The subnetpool_id attribute on subnets is not updateable, meaning that once a subnet is created it cannot be moved between subnetpools or address scopes. If a subnet was created without a subnetpool_id, it still cannot be moved into a subnetpool or address scope. This is a barrier to the adoption features like subnetpools, address scopes, and BGP. Many users likely have existing subnets that they would prefer to not destroy and re-create just for the purpose of being able to use these features.
