Hound config: disambiguate key names for projects in new namespaces

Because we use os.path.basename() for the key in the config
dictionary, openstack/project-config and zuul/project-config map to
the same key and overwrite each other, thus we only get indexing on
one or the other.

Use the full project name as the key instead.
