Since stx-metrics-server-sample-app doesn't inherit from the base
image, the Dockerfile didn't need to be changed, but to follow the
structure that was used in other apps that were migrated to debian,
some directories were changed.
Test Plan:
PASS: Debian - Build Debian docker image and upload/apply
metrics-server and metrics-server-sample-app. Verified that the app is
applied and the container is created.
PASS: CentOS - Same tests that were done on Debian.
