Ian Davis 76baeb3214 Remove support for AMIs and DO Droplets
This discontinues packer builds and stops publishing (or attempting to
publish) them to AWS / DO. These have been broken for more than 6
months, and no one seems to have complained or even noticed, which seems
to indicate they are not being used much. For cloud platfrom support, we
can optionally write docker / terraform automation that folks could use
to more easily launch instances to cloud environments instead.
