Description

Performance improvement to REST API call to update policies. Currently,

1) the update is a bit slower because of the repeated calls to DB for policy objects.

2) policy cache need not be built while updating the policy via REST API as this call if it happened to be in the timeframe of the policy download,  it is slowing down the update process.
