Juju GUI handling of empty config breaks promulgated charms

Mon Feb 20 17:40:26 UTC 2017

Deploying cassandra with the GUI. Cassandra installation will fail with the
following error.

KeyError: 'http_proxy'

The Cassandra charm expects config['http_proxy'] to return an empty string.
This is what happens when deploying Cassandra using the CLI. However,
config_get crashes because the config isn't set. running config-get in the
hooks context shows that the http_proxy config value just isn't set.
