Description of problem:

podman update --memory option not updating the memory of the running container

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

Red Hat Enterprise Linux release 8.8 (Ootpa)

Client:       Podman Engine

Version:      4.4.1

API Version:  4.4.1

Go Version:   go1.19.12

Built:        Tue Sep 19 16:01:11 2023

OS/Arch:      linux/amd64

How reproducible:

Steps to reproduce

1. on any running container execute "podman stats" It will show you the memory it consuming currently and memory it can avail. That is the default memory of the machine

ID            NAME          CPU %       MEM USAGE / LIMIT  MEM %       NET IO             BLOCK IO           PIDS        CPU TIME      AVG CPU %

8ae9b2b73438  test-purpose  0.00%       46.56MB / 1.865GB  2.50%       35.64kB / 8.835kB  235.4MB / 2.482MB  3           4.065274047s  0.04%

1. now update the memory given to the container as below.

[root@rhel8 system]# podman update --memory 1G test-purpose 

8ae9b2b73438db38b3744726f008af865bb500aeb95372759dd9d0e68930f301

1. the new allocated memory is not seen with "podman stats" 

ID            NAME          CPU %       MEM USAGE / LIMIT  MEM %       NET IO             BLOCK IO           PIDS        CPU TIME      AVG CPU %

8ae9b2b73438  test-purpose  0.03%       37.86MB / 1.865GB  2.03%       35.64kB / 8.835kB  235.4MB / 2.482MB  3           4.066264632s  0.03%

Expected results : once we update memory of a running container using "podman update --memory" command podman stats should provide us the updated limit of the memory

Actual results: No changes are seen after executing "podman run --memory etc.." in podman stats.
