> Add configuration option to exclude rules by a regex on their description

> Key: HIVE-25880

> Project: Hive
> Issue Type: New Feature
> Components: CBO

> Introduce a configuration option to exclude rules via a regex on the rule
> description, based on Calcite's
> [org.apache.calcite.plan.AbstractRelOptPlanner#setRuleDescExclusionFilter|https://github.com/apache/calcite/blob/0065d7c179b98698f018f83b0af0845a6698fc54/core/src/main/java/org/apache/calcite/plan/AbstractRelOptPlanner.java#L186].
> The motivation is to provide a quick workaround when one or more rules are
> causing issues at planning time, without code changes.
> Another use would be to quickly experiment on the impact of disabling one or
> more rules on the compute plan.
> An example of configuration would be as follows:
> {code:java}
> set
> hive.cbo.rule.exclusion.regex=HiveJoinPushTransitivePredicatesRule|HivePreFilteringRule;
> {code}
> The above configuration setting would exclude from planning both
> _HiveJoinPushTransitivePredicatesRule_ and _HivePreFilteringRule_ rules.
