RFC: monitor jobs from SQL entering final comment period

The RFC proposing a SHOW JOBS SQL statement to monitor long-running cluster jobs, like backup and restore, is entering final comment period. Due to a procedural oddity—the implementation of this RFC has already been merged in #16733—the final comment period of this RFC will only last for one day.

Thank you, @israelg99, for writing both this RFC and its implementation! Please leave comments on the PR.
