is there a way to support prefix_url when defining a blueprint.

[demoze]

Is your feature request related to a problem? Please describe.

I would like the servicebroker to be call by multiple cloud controller with a prefix. Each cloudcontroller will make a call to the broker by prefixing the url.

EG : /<plateform_id>/v2/catalog

This way the broker can handle the request base on wha call him.

The way I use to do that is by passing a url_prefix='/<pfatform_id>' in the bueprint or when registering the bueprint.

openbrokerapi.api.get_blueprint() has no url_prefix option , and trying to do it with app.register_blueprint(api_blueprint, url_prefix='/') will failed later when the request come in.

Describe the solution you'd like
It will be nice, to be able to have url_prefix option on api.get_bleuprint() and add support to handle it.
