cql_statement is a class representing a prepared statement in Scylla. It is used concurrently during execution, so it is important that its change is not changed by execution. Add const qualifier to the execution methods family, throghout the cql hierarchy. Mark a few places which do mutate prepared statement state during execution as mutable. While these are not affecting production today, as code ages, they may become a source of latent bugs and should be moved out of the prepared state or evaluated at prepare eventually: cf_property_defs::_compaction_strategy_class list_permissions_statement::_resource permission_altering_statement::_resource property_definitions::_properties select_statement::_opts
