[Tagging] Tagging of pitches within a campsite

[Bryce Nesbitt]

I'm opening discussion on how to best tag individual pitch numbers
within a campsite.
There are a variety of schemes in use from "tourism=caravan_site" on each
node to "campsite=pitch,ref=XXX".

This scheme seems to work fairly well:

But differs from the wiki.

(note good rendering, but missing the dump station,
and the ranger station (also reception, park HQ, and grocery).
