Fix Backups

[bdwyertech]

The DataMap classes addconfig method was putting the config directory under a config key, rather than data_dir key which is referenced by the restore process.

Attempt to address #26 and https://github.com/chef/chef-server/issues/1020

As you can see in the manifest below, the services have a data_dir defined, but configs does not.
