Report syncer status through sync target conditions before it is ready

[sttts]

Debugging syncer problems is hard because it does not report anything until it is fully ready. We want it to set conditions much earlier.

Can you please assign this to me? I would like to give it a try :)

@sm43 sure! Could you please write down a little bit about what/where you plan to implement the condition updates, so we can get rough agreement on the approach before you dive in to coding? Thanks!

hello, due to time constraints I won't be able to do this. If this is urgent please unassign so that someone else can pick it up. Sorry for the delay. If not urgent I will give it try soon. Thanks.
