Add $cron_run global set to TRUE during cron runs for modules/developers

Thank you for sharing your idea for improving Drupal.

We are working to decide if this proposal meets the Criteria for evaluating proposed changes. There hasn't been any discussion here for over 8 years which suggests that this has either been implemented or there is no community support. Your thoughts on this will allow a decision to be made.

Since we need more information to move forward with this issue, the status is now Postponed (maintainer needs more info). If we don't receive additional information to help with the issue, it may be closed after three months.

Thanks!

Since there's been no follow up in 3+ months going to close this one out, but if still a desired feature please re-open. This one will need a summary update.

Thanks!
