Retire DNS server, ns-aws.sslip.io

Browse Source 
The torrent of traffic I'm receiving has caused my AWS bill to spike
from $9 to $148, all of the increase due to bandwidth charges.

I'm still maintaining ns-aws; the VM still continue to run, and continue
to serve web traffic, and maintain its hostname and IP addresses;
however, it will no longer be in the list of NS records for sslip.io.

There are much less expensive hosting providers. OVH is my current
favorite.
