[tor-relays] List purpose and moderation

[grarpamp]

Sorry but if a Tor friendly commercial, non profit, volunteer, or
whatever other type of vendor / provider wants to come here
and announce [or solicit mutual development of more amenable
custom] hosting solutions and services for tor relays... that's
valuable and fine.

In no small part because... for the duration in which placing
nodes in such locations / using the services continues to
make sense... it saves [prospective] relay operators time
scouring the net for hosters and getting denied service,
shutdown later, etc.
