Any function that may create a request now has a IRequestOwner& parameter, and uses the Begin and End functions on the owner to manage the lifetime of any requests that it creates, as well as using End to invoke the completion callback for any request which has one.
The new FRequestBarrier may be used to block a group from being considered complete in a scope where more requests may be added to it.

* Rename FRequest -> FZenHttpRequest to make it easier to move the implementation elsewhere
* Simplified implementation of PUT/HEAD/DELETE operations by turning template functions into plain member functions to make it easier to hide the implementation details when the class is moved into a header
