[SPARK-20213][SQL][follow-up] introduce SQLExecution.ignoreNestedExecutionId ## What changes were proposed in this pull request? in https://github.com/apache/spark/pull/18064, to work around the nested sql execution id issue, we introduced several internal methods in `Dataset`, like `collectInternal`, `countInternal`, `showInternal`, etc., to avoid nested execution id. However, this approach has poor expansibility. When we hit other nested execution id cases, we may need to add more internal methods in `Dataset`. Our goal is to ignore the nested execution id in some cases, and we can have a better approach to achieve this goal, by introducing `SQLExecution.ignoreNestedExecutionId`. Whenever we find a place which needs to ignore the nested execution, we can just wrap the action with `SQLExecution.ignoreNestedExecutionId`, and this is more expansible than the previous approach. The idea comes from https://github.com/apache/spark/pull/17540/files#diff-ab49028253e599e6e74cc4f4dcb2e3a8R57 by @rdblue ## How was this patch tested? existing tests.
