[Tagging] Fire hydrants split

Thank you for splitting it.

I think it is worth to  think about splitting the two proposals in a 
different way:

One for adding new keys (like flow_rate, water_source) and the other one 
for migrating the fire_hydrant:* keys to something else.

I see two main reasons for it:

1. Migration

According to the huge number of affected nodes (~300k for 
fire_hydrant:position=*) [1] I'm afraid that a lot of voters will oppose 
the proposal due to
the huge impact of it. In this case we would also not have the well 
discussed new tags and need to start a new proposal.

2. The part 2 proposal works only if part is agreed on. At least for 
pump and suction_head keys. So a rejected part 1 proposal makes the 
second more or less useless.


So I would put the changes from part 2  (pump, suction_head, wrench) in 
part 1 and move the whole migration issues from part 1 to part 2

+1
