Merge lp:~freyes/charms/trusty/nova-cloud-controller/lp1387073 into lp:~openstack-charmers-archive/charms/trusty/nova-cloud-controller/next

[Felipe Reyes]

Dear OpenStack Charmers,

This MP exposes the scheduler_default_filters from nova.conf as a config option. By default uses the same set of filters that was hardcoded in the template.

This MP adds a basic unit test for NovaConfigContext class.

Best Regards,

The amulet fail looks to do with a known race and other tests did pass. The lint error is a minor charm proof issue unrelated to this change, so LGTM! Thanks for the mp
