This patch is required to fix the nightly deployment:
* We need to use the exact docker image tag what we built earlier
* Migration should be full instead of snapshot (snapshot couldn't update existing, but older dbs)

Earthly is a build tool, it uses buildkitd to create reproducable and highly cacheable builds.
It is used by a new experimental nightly build to easily create storj-up images. (but can be used for any ad-hoc storj-up cluster to create the images).
To make the nightly more robust, I would prefer to commit the helper files (today I do a rebase every time, but sometimes it fails).
