Make query execution truly asynchronous (#83)

Browse Source 
The two main changes in this pull request:
Launching query execution as an asynchronous task that performs a callback upon completion or failure of a query. (Which also sets us up for callbacks progressive results)
Moving away from using the Result of a query execution to return an error. Instead we'll use an error event to return an error
Additionally, some nice refactoring and cleaning up of the unit tests to take advantage of the cool RequestContext mock tooling by @kevcunnane

* Initial commit of refactor to run execution truely asynchronously

* Moving the storage of the task into Query class

Callbacks for completion of a query and failure of a query are setup as
events in the Query class. This actually sets us up for a very nice
framework for adding batch and resultset completion callbacks.

However, this also exposes a problem with cancelling queries and returning
errors -- we don't properly handle errors during execution of a query
(aside from DB errors).

* Wrapping things up in order to submit for code review

* Adding fixes as per comments
