Add negative cache entry after deleting object/folderCache entry update

[codechanges]

Description

After deleting an object or folder populate negative cache immediately.
This will save call/s to a backend to verify existence of a said object/folder resulting in perf gains.

Added invalidate logic in case of error to better handle all scenarios in case delete[object/folder] fails.

Link to the issue in case of a bug fix.

Please add the integration test label to validate that all tests are functioning correctly. Also, please include a composite test for this scenario.

Added integration test label. I think that, not handling error properly is a wider issue and needs to be taken care of in a different PR which should include composite test. I will raise a separate bug for the same and keep the scope of this PR limited for now.
