Kevin Benton a38b5df5cd Set IPset hash type to 'net' instead of 'ip' 
The previous hash type was 'ip' and this caused a major
issue with the allowed address pairs extension since it
results in CIDRs being passed to ipset. When the hash type
is 'ip', a CIDR is completely enumerated into all of its
addresses so 10.100.0.0/16 results in ~65k entries. This
meant a single allowed_address_pairs entry could easily
exhaust an entire set.

This patch changes the hash type to 'net', which is designed
to handle a CIDRs as a single entry.

This patch also changes the names of the ipsets because
creating an ipset with different parameters will cause an
error and our ipset manager code isn't robust enough to handle
that at this time. There is another ongoing patch to fix
that but it won't be ready in time.[1]

The related bug was closed by increasing the set limit, which
did alleviate the problem. However, this change would also
address the issue because the gate tests run an allowed address
pairs extension test with the CIDR mentioned above.
