Updates to epee HTTP client code

  - http_simple_client now uses std::chrono for timeouts
  - http_simple_client accepts timeouts per connect / invoke call
  - shortened names of epee http invoke functions
  - invoke command functions only take relative path, connection
    is not automatically performed
