Debian: kernel and initrd image patching are not synced

[Jessica Castelino]

Brief Description
---------------------------------------------------------------------------------------------
Kernel and initrd patching works today for an existing installed system.

The issue is that because the /var/pxeboot/rel-xx.xx and /var/www/pages/feed/rel-xx.xx dirs which contain the kernel/initrd images used to do system node installs are not provisioned by ostree automatically but rather by the kickstart, any kernel/initrd patch changes need to be synced to these directories before we allow any host re-installs or new installs so they get the patch current images.

Thus, after patching of a controller, we need a script to run which syncs the kernel/initrd images from /boot to the /var/pxeboot/rel-xx.xx and feed dir before we install new nodes or re-install any existing nodes so that they get the patch current kernel/initrd images.

Severity
---------------------------------------------------------------------------------------------
Minor

Steps to Reproduce
---------------------------------------------------------------------------------------------
Apply and install a kernel patch

Expected Behavior
---------------------------------------------------------------------------------------------
The kernel and intrd images should be synced to /boot to the /var/pxeboot/rel-xx.xx and feed dir before we install new nodes or re-install any existing nodes

Actual Behavior
---------------------------------------------------------------------------------------------
The kernel and intrd images are not synced to /boot to the /var/pxeboot/rel-xx.xx and feed dir before we install new nodes or re-install any existing nodes

Reproducibility
---------------------------------------------------------------------------------------------
100% reproducible

Review: https://review.opendev.org/c/starlingx/update/+/864063
Reason: The script that patching was supposed to run as a part of this commit, is run during reboot (/etc/init.d/pxeboot_feed.sh). Since kernel patches are always RR, this script will run on host-unlock and we don't need additional changes within patch-agent for it.
