This change reorganizes the source directories of the ptp-notification's
containers: locationservice; notificationservice; notificationclient, to
be reused by both CentOS and Debian Dockerfiles to build the images
having the corresponding OS-specific base, together with the new files
used to build images for Debian.
Tests:
PASS: Build images of the 3 containers for Debian
PASS: Upload and apply changed ptp-notification application to pull
Debian images from private repository (since final tag is
not possible yet) in a Debian AIO-SX environment
Regression:
PASS: Build images of the 3 containers for CentOS
