[WIP] End the request not the response when dispose is called

[WyriHaximus]

Calling close on response will immediately close the connection, while calling end on the request will send any buffered messages to the other end and then close the connection.

Should aid with #9

• Correctly end connection
• Add tests

@mbonneau Any idea how to test this?

[mbonneau]

I am now having seconds thoughts about whether the connection should be closed when the subscriber count goes from 1 -> 0.

It may be a valid use case to only send - or to dispose of a MessageSubject subscription while still sending.

Maybe this could be an option? or maybe it would be the user's responsibility to publish the connection so it doesn't dispose if they want to keep it open?

Personally in my use case I want it closed. And I can't think of a use case where I would want to keep it open. But making it configurable is a good way to go about this 👍
