Comment 8 for bug 1684049

When we do juju bootstrap --bootstrap-constraints the settings are set for the first controller and then for all machines created with enable-ha, except for those explicitly provided with --to (and this should not work on versions without this fix).

Another problem is with --constraints on bootstrap - those are stored as model constraints and added independently from --bootstrap-constraints - I've added a separate bug for that https://bugs.launchpad.net/juju/+bug/1706688
