Test WebSockets in Tentacle Integration tests

[LukeButters]

Currently none of the Tentacle Integration tests cover communicating to tentacle over polling websockets. Which is a supported use case.

To complete this we would need to:

• Improve the Tentacle builders to support web sockets.
• Include web socket as a standard type of tentacle in TentacleTypesToTest and test inputs. Doing this results in existing tests testing with websockets. We shouldn't need any additional tests to be added.
