A flow is two names. Its id is which flow it is: the directory, the argument
every method here takes, and never changed once given. Its key, ``name``, is
the namespace of its messages and unique among flows. A flow from before ids
existed has its key as its id (`fluksio.flow.identity`), and so does every new

Both read a flow store directory and change nothing. `ls` lists its flows and
dashboards by id, key and kind, which helps when reading a backup.
`migrate --dry-run` runs the check the engine makes when it starts and prints
what the start would migrate, or why it would refuse to start. It exits with 1

itself, on its next start.
