BUG-5280: add READY protocol
In order to make chained transactions work with remoting
we need a way for the frontend to propagate the ready state
to the backend. This patch adds a READY protocol, which acts
as a preparatory stage before the 'real' protocol kicks in.
With that the backend state is properly updated to reflect
state transitions on the frontend and we do not need to play
weird future-based delays in the frontend, which would be
exceedingly complex.
