"juju deploy" writes "Deploy of bundle completed." stderr

[Paul Collins]

When deploying a bundle with "juju deploy", the final "Deploy of bundle completed." is written to stderr.

This may be related to LP:1869795, but seems to be a different case, since this is not machine-readable output, and it doesn't show up in --show-log.

It's a similar underlying root cause - if the code uses ctx.Infof() to record output, it goes to log output if --quiet is used, else stderr. With --verbose it's the opposite.

This has been discussed in the past, and we have agreed that we can fix this in Juju 3.0, but we should not make this change in a Juju 2 point release.
