Update Browseable documentation in case of SAML in use
Apache::Session::Browseable is required to avoid downloading all sessions when restrictions are used (~ searchOn($_whatToTrace)). But when SAML is used, requests are done on other fields : ProxyID, _nameID, _saml_id and ID (in samlStorage which points to globalStorage by default).
So please update "browseablesessionbackend" doc to explain how to optimize this.
