Although std::map::find is not guaranteed to be noexcept it depends on the comperator used and in this case comparing application_state is noexcept. Therefore, we can safely mark get_application_state_ptr noexcept. is_cql_ready depends on get_application_state_ptr and otherwise handles an exceptions boost::lexical_cast so it can be marked noexcept as well.
