charm has no way to report error state

[Jay R. Wren]

https://juju.ubuntu.com/docs/authors-hook-errors.html says "If any of your hooks returns a non-zero exit code, juju will stop managing the unit directly and will wait for user intervention. This is a Bad Thing, and you should make every effort to avoid it"

I have a charm which could be configured in a state which is error. It should be possible to return an error message so that a user knows what happened.
e.g.
My config takes a ppa, but I typed it wrong. Charm would say "invalid ppa" and this could show in juju status.

This is fixed with juju workload status feature.
