Property "retention.policy.agebaseddelete.limit" is a mandatory property and must contain a valid duration e.g. "hours(1)"
+Retention frequency is not a mandatory parameter. If user doesn't specify the frequency in the retention stage then
+it doesn't fallback to old retention policy frequency. Its default value is set to 6 hours if feed frequency is less

In future, we will allow more customisation like customising how to choose instances to be deleted through this method.
