Fixed execute cli-handler to use the new execute method on client

                errs.error(obj['id'], 'bad role')

                continue

            try:

                objcon = self.server.get_connection(obj['id'])

                client = self.server.get_client(obj['id'])

            except KeyError:

                errs.error(obj['id'], 'node not connected')

            else:

                returned = objcon.connection.call('execute_command', command)

                returned = client.execute(command)

                errs.success(obj['id'], 'command executed', output=returned)

        return errs.get_dict()
