Expose API to disable inherited settings (or disable them by default)

We are using Bitbucket API to create and configure repositories automatically via script.

We cannot do it anymore now, because when we try to set the branching model we get this error:

{'type': 'error', 'error': {'message': 'Cannot update repository branching model when inherited project settings is on'}} 

The only way to avoid this is to disable the flag manually from the console (because it calls an internal and private API).

We would like the possibility to have an external API as well, or at least to turn off the "Enable inherited settings" flag by default instead of having it on.
