[Supervisor][fabric] Fix the error message for non-present fabric card during config reload on SUP

[mlok-nokia]

Why I did it

After a config reload or a config load_minigraph we see the following error messages in the syslog for non existing fabric cards:

ixre-cpm-chassis19 ERR container: docker cmd: stop for syncd0 failed with 404 Client Error for http+docker://localhost/v1.43/containers/syncd0/json: Not Found ("No such container: syncd0")
ixre-cpm-chassis19 ERR container: docker cmd: stop for syncd1 failed with 404 Client Error for http+docker://localhost/v1.43/containers/syncd1/json: Not Found ("No such container: syncd1")

On Sup, for non-existing Fabric slot, its related swss and syncd containers have not been created yet although its related services have been started.

How I did it

Added checking to the docker_image_ctrl.j2 stop() method. This change adds code to check if related container exists, then call container stop. Otherwise, just log a message to indicate that "No such container". Fixes #19765

How to verify it

1. execute "config reload" on SUP which contains empty Fabric slot.
2. The following related error message should not be seen in syslog

ixre-cpm-chassis19 ERR container: docker cmd: stop for syncd0 failed with 404 Client Error for http+docker://localhost/v1.43/containers/syncd0/json: Not Found ("No such container: syncd0")
ixre-cpm-chassis19 ERR container: docker cmd: stop for syncd1 failed with 404 Client Error for http+docker://localhost/v1.43/containers/syncd1/json: Not Found ("No such container: syncd1")

3. Instead, the following message should be shown for the related empty Fabric slot

2024 Sep 19 17:45:18.339106 ixre-cpm-chassis15 INFO swss.sh[2024819]: container stop swss0 -- No such container: swss0
2024 Sep 19 17:45:20.633519 ixre-cpm-chassis15 INFO syncd.sh[2025664]: container stop syncd0 -- No such container: syncd0

@abdosi I have changed the code to be more generic to check if docker doesn't exist, log a message. Please review it again.
