Extend the tracking issue command to close the old issue
When a RM executes
/chatops run release tracking_issue --security it'll create a new security release tracking issue, but it'll not close the old one. This leads to have unnecessary steps on the security release template such as a close the current release tracking issue and create a new one.
As a follow up of #1144 (closed)
Extend the security release tracking command to close the old one security release tracking issue.
