[Tagging] Proposed feature - Voting - electricity

The idea of tagging this is that if someone, e.g a traveller, shows up 
to charge something they can reasonably assume if something is tagged 
electricity=yes that they will be able to charge their phone/laptop etc. 
If something is tagged as intermittent, then there is a significant 
chance that usage of electricity won't be possible.  For context, people 
in the US experience 1.1 outages/yr and thus most sources there would 
likely be classified as reliable, whereas a country like Ghana 
experiences 1.5 interruptions per week.

I don't intend for this to be used to map if someone should really 
consider investing in a UPS - no one should need to hook up there 
hospital devices on a whim in a cafe and then need to have a perfect 
power supply. Tagging the quality of electricity is outside of the scope 
of the proposal and if necessary a separate one should be drawn up.

Also, scheduled power cuts are not included in the intermittent outage 
count - the schedule should then be tagged as electricity:conditional=*
