Ping the appropriate release managers on new security release tracking issues
Overview
As we move to multiple security releases per month, we need to be sure we are pinging the correct release managers on the issues when they are generated.
Currently, when the security release tracking issue is created, it is assigned to the active release managers and the next release managers are pinged on the issue requesting they set the due date.
Proposal
Assing and ping the release managers associated with the release date. The tracking issue assumes a new planned security release will be scheduled every 2 weeks if the multiple_security_releases
FF is enabled (logic can be based on #19839 (closed)). The associated release managers with the release scheduled in two weeks can be fetched, assigned and pinged in the respective tracking issue.
This should be under a feature flag.
