.dockerignore keeps .git/ out of the build context, so the in-image publish had
no repository and AssemblyInformationalVersion (Telemetry service.version) was a
bare 1.0.0. The Dockerfile now takes ARG SOURCE_REVISION and passes it to
dotnet publish as SourceRevisionId; docker-compose.yml forwards it as a build arg
for the host and migrator images; the new docker-dev/compose.sh wrapper exports
git rev-parse HEAD (suffixed -dirty for an uncommitted tree; an explicit value
wins) and runs docker compose with the base file. Without the arg the build
still succeeds as 1.0.0. The ARG sits after restore so a new commit does not
bust the restore layer. Mirrors ScadaBridge 7e34d7c2 (ScadaBridge#134).
