Replacing Qt Signal Slot with Boost Signals2

[sima-fastly]

This is the first PR in a series of PRs to replace Qt signal & slot system with Boost Signals2.

In this PR we are replacing qt signal slots in the very top layer of all services quit & hup signals.

Tested manually

We should also remove the Q_OBJECT macro from class definitions as well as the QObject inheritance.

I agree, that can be done after Qt signal/slot cleanup?

That's fine but do we know if such removal is possible? It only makes sense to move to boost if we can actually get off of QObject. It would be good to try this locally at least, and then the change could go in a later PR.

from what I understand so far, I am fairly certain it is possible but I am gonna have to peel back layers one by one which will take weeks.
