Refractor hooks for move macros

Created by: dschick

as discussed yesterday in the follow-up meeting, I am already trying to refector parts of the macros for movements based on #1480

However, I just noticed that besides moving the hints to the new base class MoveMacro which then inherits from Macro and Hookable there is not much to refractor, since we do not define what actually happens in the move-macros, e.g. which underlying macro is called. So umv calls mv but umvr calls umv and so on. And we can also not define that for any new Macros which developers/users will come up.

As I see it, it is most "effort" to hand the hooks to the final mv macro, which currenlty requires

mv, _ = self.createMacro('umv', motor_pos_list)
mv._setHooks(self.hooks)
self.runMacro(mv)

instead of self.executeMacro('umv', motor_pos_list)

Regarding the self.motors one could ask about that from the called macro, right? So refering to the line above, one could add at the end: self.motors = mv.motors

As @reszelaz mentioned in his comment self.motors will be provided by the mv macro in the pre-move and post-move hooks. We agreed to stil implement this property for all move macros for consistency. But should it be available already in the prepare or in the run method? I have move the filling of self.motors in the mv macro already into its prepare method.

So any ideas how to simplify this further?
