TEZ-4643: Enforce speculation configuration to prevent execution on normal tasks.
A configuration meant to distinguish between slow and normal task attempts is not working correctly. This causes the speculation mechanism to target normal tasks as well, wasting considerable resources. This fix ensures the configuration is enforced, limiting speculative execution to only outlier or slow tasks.
