Add the ability to check off the "Application requires approval" and "Service subscription requires approval" checkboxes when editing or creating application plans via the API.

Customer Use Case:

We fully deploy an api in 3scale using the 3scale REST API using a swagger file and an extra cfg file with some settings not in included in the swagger file.
An API can be hidden, public or sector so that developer in the developer portal sees the api in the list or not or when he subscribes he needs to be approved by Customer or not.
For that reason I need to be able to check the "requires approval" for a application or service plan.
Until now this is the only functionality I miss in the REST API.
