Remove executeRequest from HttpManager. It has some show-stopping bugs, like leaking semaphore counts (since it never waited) and being generally thread-unsafe. Implementing it in a way that would be asynchronous and thread-safe is a non-trivial task, so I've opted to remove it and change callers to use executeRequestSynchronously.
