Please update cassandra-charm with the latest charm-helpers

[Brian Murray]

I'm seeing this traceback when trying to deploy cassandra:

It's because the http and https proxy are set to squid.internal and no_proxy wasn't being set in the environment. This has been fixed with the following charmhelpers update:

https://github.com/juju/charm-helpers/pull/627

Please update the cassandra charm with this change.
