Add streaming GAQL query endpoint

[PaulLockhart]

Would be super nice to be able to open a search stream via a GAQL query rather than the special request object, similarly to how you can do this with the regular query-based search endpoint.

Wondering if this is already possible, and if not it would be a very useful feature.

Interesting idea @PaulLockhart, do you mind if I ask why you would prefer to use GAQL over the report options?

Personally I use GAQL as there are a lot of Google's own examples over their docs

I don't particularly mind the library default implementation if building a project from scratch, but I think using GAQL makes requests more universal and language independent, and makes it easier to pick up and use the library for an existing code base that already has GAQL queries.

@arditti @PaulLockhart We will be upgrading the library to v11 of the API next week. I'll have a look into it then, and if it isn't too much work I'll try to fit this in for you.
