This copies the logic from last_tor_version.sh and last_torsocks_version.sh
into the Dockerfile itself. The Tor version can still be specified with the
`tor_version` and `torsocks_version` arguments, as before. If these arguments
are missing, the last versions are determined by the regular expression.
This has a couple of advantages:
1) Users need not have git, make or docker-compose installed to build the image.
2) Users can build the image entirely inside a container which reduces the trust
needed in the safety of the build instructions.
3) `git tag` is much quicker than `git ls-remote` since it operates on local data.
This has two purposes:
1) The 'torify' wrapper is already included, and it needs torsocks.
2) Use torsocks for health checking your onion service like this:
healthcheck:
test: ["CMD-SHELL", "torsocks nc -z <onion address> <port> || exit 1"]
interval: 2m
