Using AWS is what causes it so using AWS can be what fixes it, too.

... This breaks the tie, thx to https://github.com/DBCDK/morph/issues/146

Just require hostName and domain instead of an extra publicIPv4 option.  Leave
behind a similar option, `publicAddress`, just in case it needs to be
overridden at some point, but stop supplying a value for it anywhere.

Put its contents in it and then use them from there instead of importing them
all over the rest of the code.

Also change the `domain` parameter for Grafana to always
use that beautiful name - besides display it's cosmetic anyway
IIANM so I'll not parametrize it for now.

For consistency reasons: Even if they had a perfectly good swap
partition already, and also for AWS hosts.

The original domain got some state created for it by certbot.  The
certificates are anchored to `payments.privatestorage.io` in the filesystem.
The code handling these domains uses the first domain name in the list to find
the certificates, so make it match the filesystem state.
