Added a timeout to the https ping

For those not using https who might have it firewalled, this request without a timeout causes significant delay. Adding a moderately generous timeout shouldn't affect anyone negatively, but will make things a bit nicer otherwise.

Stop timeout should be added to the request timeout

Using the max of the stop timeout and request timeout did not entirely
make sure that a stop timeout greater than a request timeout wouldn't
fail prematurely with a HTTPTimeout exception. The correct behavior is
to add the timeouts together, as the stop timeout is understood to be
part of the "request processing time". Any transport-level timeout thus
comes in addition to that.
