Run now takes a context as well as a statebag. We'll assign the context
to the blank identifier to prevent namespace collisions. We'll let the
step authors opt-in to using the context.
`find . -iname "step_*.go" -exec gsed -i'' 's/func \(.*\)Run(/func \1Run(_ context.Context, /' {} \;`
Before we couldn't be sure if we were a permanent container or not.
Now we explicitly pass this on the command line so we don't depend on the
extra logic in `lxc publish --force` for ephemeral handling.
This means we avoid restarting the container after we publish
since we tear it down right away anyhow.
Likewise, there was sometimes a race which prevented the deletion
while the container was in a boot stage.
