This update adds a METADATA file inside the plugins directory.
The app-gen-tool embedded with the stx-9 ISO was failing due
to pbr issues with the package version. Adding this METADATA
resolves the problem. Also updated the build method from
easy_install to build and corrected an error from the
"transform_rel_path_into_abs_path" function..
Test Plan:
PASS: app-gen-tool embbed with stx-9 now runs with
the --package-only flag without errors.
PASS: poc-starlingx-app application apply works
fine after the METADATA file being added.
