Override "after" key deprecated by "dependent_apps"

Adjust the metadata.yaml of the intel-device-plugins-operator
application to no longer use the after key and instead use
the "dependent_apps" key.

This new feature installs the NFD app if you need to install
intel-device-plugins-operator and NFD is not already installed.

Test Plan:
PASS: build-pkgs && build-image
PASS: fresh install AIO-SX
PASS: Upload, remove, apply and delete
      intel-device-plugins-operator app
PASS: Update and rollback intel-device-plugins-operator app
PASS: NFD was triggered to upload and apply automatically after the
      intel-device-plugins-operator apply process started.
