Subject: [PATCH] Support dockerd in-service patching with EXAMPLE_DOCKER
 script

This adds the EXAMPLE_DOCKER in-service patching script.
Packaging currently for CentOS, but script itself is generic.

The docker.service has required patching, so this supports future
patching.

Closes-Bug: 1996916
Depends-On: https://review.opendev.org/c/starlingx/utilities/+/865731

Test Plan:
PASS: CentOS: Apply/remove designer in-service patch including
      EXAMPLE_DOCKER and verify docker.service restarts.
