Implement deleteStream command on client connection

[jbreich]

Hello, I implemented the possibility to send a deleteStream command on a client connection. The aim is to properly end a stream. I am not sure it is the best way to do it so I am open to your feedbacks.

Thank you for the pull request! I will merge it.
In order to increase coverage, I plan to add tests, including for existing code, and would like to create a release tag either today or tomorrow. (If this is urgent, please let me know in the comments.)

Thank you for your quick reponse. It is not urgent no problem

I added a commit about a leak on the client connection, sorry. I can put that in another branch if you want ?

[yutopp]

I apologize for the delay in my action. No problem at all! Thank you for your additional corrections.
