Description of problem:
=========================
When you rename a cold file, the file should get heated up and eventually move
to hot tier. But that is not happening.
This is a case of metadata change which means ideally it should increase the
counter of file to get heated up, but is not happening

Version-Release number of selected component (if applicable):
============================================================

Steps to Reproduce:
===================
1.create a regular volume and start it.
2.set following options
 performance.quick-read: off
performance.io-cache: off

3.Now attach a tier and enable features.ctr-enabled.
4. fuse mount the volume
5. Create a file and check if it is created in hot tier(works as expected)
6.  Now wait for say about 3min by keeping the setup idle.
7. Now the file should have been moved to cold tier(works as expected)
8.Now do a rename of the file

Actual results:
===============
rename passes, but the file doesnt get heated,even though the ctime changes,
which is a metadata change action

Note:
I haven't set promote/demote freq. Which means the default time should be about
120sec
Also, I haven't turned on  features.record-counters or read/write threshold
counters, which means I file should get heated if modified even once.


Logs will be attached



Expected results:
