Add documentation for available arguments for method and query

[Bekt]

Similar to: https://cloud.google.com/appengine/docs/python/endpoints/create_api

It would be nice to have detailed documentation of what all arguments EndpointsModel.method and EndpointsModel.query take. Currently, I'm reading the source and having hard time finding what is what and why from **kwargs.

The above page does a good jobs of documenting (look for @endpoints.api and @endpoints.method)

I agree. A start may be some user-generated content in the Wiki: https://github.com/GoogleCloudPlatform/endpoints-proto-datastore/wiki

I'm happy to answer questions if you have any, but don't have bandwidth for something like this at the moment.
