[arin-ppml] Revised: ARIN-2017-4: Remove Reciprocity

[David R Huberman]

ARIN-based network operators who are responsible for multi-continent IP 
networks need to be able to move ARIN-registered numbers from ARIN to 
LACNIC and AFRINIC for our datacenters in those regions.  This need is to 
allow us to achieve legal compliance and network engineering goals.

This draft policy meets that need, has safeguards against imbalance, and 
is respectful of the wishes of two RIR communities. Quoting David Farmer:

"In the long-run I totally believe LACNIC and AFRINIC should approve 
reciprocal transfer policies. However, we need to give them room to decide 
this for themselves, it is arrogant and inconsiderate of the facts for us 
to dictate a reciprocal transfer policy to them.  If they feel they need 
to start with a one-way transfer policy, there is logic to such a 
strategy, and the current facts seem to justify at least some caution on 
their part."
