KeyError for 'machine-status' while lint against juju status oputput from python-libjuju

[esunar]

ouput from model.get_status in python-libjuju doesn't have machine-status in it, while juju status --format json does. Using it for juju-lint will fail with KeyError:

Issue has been reported on python-libjuju side:

https://github.com/juju/python-libjuju/issues/387

In the meanwhile, we can also avoid such KeyError from juju-lint itself.

(by guoqiao) Above 2 json file are from same juju model. First one doesn't have "machine-status" while second one does.

[esunar]

(by guoqiao) Just noticed juju-status is missing too.

(by ec0) This should have been handled by the refactor, please reopen a new bug if you find additional key errors.
