This is clearly some kind of race condition because retrying the hook is
successful.

In enable_livestatus_config, it is creating this directory and then
trying to chown livestatus_path, but it doesn't look like anything has
made a socket there. I don't know what is supposed to.
This results in a hook failure. The application eventually gets to
Ready, but this is enough to trip juju wait.
