Shared conversation_id within HA

Add default value for “conversation_id” in assist pipeline, or create an entity named “current_conversation_id”.

By doing this, we will be able to start a random conversation with conversation_id attached to it, which would essentially enable multi-turn, connected automation (voice assistant and automation are now connected).

As you can see, by using the same conversation_id, the information is connected between voice assistant and “conversation” action which can be used in scripts and automation.

I think it is already been worked on!
At least in dev branch now!

How soon are we going to see this change?
Keen to have a global conversation ID that can be tracked and used!

@balloob Thank you for your amazing work!
