11 This method exposes the public ssh keys for a slice's slivers.
12 It expects a slice name or id, and returns a dictionary on hostnames.
13 This method is designed to help third-party software authenticate
14 slivers (e.g. the OMF Experiment Controller).
15 For this reason it is accessible with anonymous authentication.
