Title: Clean up around HttpEngine.sendRequest().

Move gateway timeout failures to CacheStrategy, and inline
methods nearby for a strict top-to-bottom flow in this method.

It becomes more obvious that the end of sendRequest has two
cases: we need a connection (opening if necessary) or we don't
need a connection (closing if necessary). Previously this was
true but not as explicit.
