Pass root answers.conf to inherited applications.

[cdrage]

As per @vpavlin 's comment on projectatomic/nulecule#185

We should be passing the root answers.conf to all inherited applications

Specifically, this line of code:

https://github.com/projectatomic/atomicapp/blob/master/atomicapp/nulecule/base.py#L313

Thus when deploying an inherited application, instead of using the default namespace (currently just default) we will use the namespace that has been provided within answers.conf.

This will be taken care by #423

Currently, we do pass the entire config data to all the nodes. So, a node can always checkup for the namespace param in config['general'].

@cdrage ping?

[cdrage]

@rtnpro Yeah, you're right, but we don't pass all the information yet (for ex. if we add params about persistent storage and such onto the graph it's not passed onto the provider) just the general configuration information.

@cdrage because persistent storage is not part of the config data, right now :) We need to syncup to discuss on this.
