[himanshu-kun]

How to categorize this issue?

/area open-source /area dev-productivity /kind enhancement /priority 3

What would you like to be added:

We need to add issue template for the activity

• Make a release of MCM

An issue with this template should be created per milestone and release responsible should be assigned that issue.

Why is this needed:

Today when we release a minor version MCM , there are many tasks which should be performed before and after the release. This issue template will have a checklist of all such tasks.
