New and possibly final version after MB suggestions and LHCONE discussion: https://twiki.cern.ch/twiki/bin/view/LHCONE/LhcOneAup-revised

Highlights:

- RC Site: a Resource Contributing site participating in and formally tied to one or more of a participating Collaborations
- LHCONE Site: a RC site connected to the LHCONE L3VPN service;
(replaced  "HEP site" with more generic "RC site")

The LHCONE community accepts or rejects based on the impact on the LHCONE. Among criteria to be used in the evaluation:
    the collaboration MUST have an established relationship with WLCG 
(replaced "must be related to Particle Physics" with " must have an established relationship with WLCG")

Other computing resources not directly owned by a RC site can be connected to LHCONE, like:
   -  High Performance Computing (HPC):
        - are eligible to get part of LHCONE as long as the HPC system belongs to a LHCONE site or has an agreement with a RC site of one of the LHCONE collaborations
        - resources not yet connected to LHCONE have to follow the connection request procedure 
    - Cloud Resources:
        - cloud resources are only used for WLCG computing
        - their IP prefixes are dedicated to LHCONE purpose
        - their use is and their security provisions are under the responsibility of the LHCONE site admin and MUST be consistent with the present AUP and the WLCG standard
        - any other kind of cloud resources that doesn't fulfill these requirements has to be routed in the standard way (either general R&E IP or commodity internet) 
(addition to "Eligibility for becoming a LHCONE Site")
