Actually, `ipsec reload` always removed and re-added ALL connections not
only the changed ones.  Use `ipsec update` to only reload the changed

Since 5.0.1 removed and changed connections with `auto=route` are
unrouted (same as `ipsec unroute <name>`), this properly allows changing
`left|rightsubnet` or `auto` for such connections.  But if you use
`reload` instead of `update` all connections are considered to have
changed, so all connections are unrouted and routed again.
