Time-based internal index patterns queried as wildcard index patternsedit

Details: Time-based interval index patterns were deprecated in 5.x. In 6.x, you could no longer create time-based interval index patterns, but they continued to function as expected. In 7.2, functionality has changed such that Kibana will automatically query a time-based interval index pattern as a wildcard index pattern. Support for time-based index patterns will be removed in 8.0. You can migrate your time-based index patterns to a wildcard pattern to prepare for this change.

Impact: If you query a time-based index pattern, that query will now be performed on the root wildcard term. For example, a query on an index pattern such as [logstash-]YYYY.MM.DD will now query all indices that match logstash-*.
