+Enhancement: Functionality to map home directory to different storage providers
+
+We added a parameter in reva that allows us to redirect /home requests to
+different storage providers based on a mapping derived from the user attributes,
+which was previously not possible since we hardcode the /home path for all
+users. This PR adds the config for that parameter.
