Phosphorus migration

Phosphorus migration

Bump upstreams dependencies to:
- odlparent: 9.0.5
- mdsal: 8.0.4
- netconf: 2.0.3

Perform some code adaptations in all modules to allow project building.
- remove number of useless calls to .toString()
- fix issue regarding Tp Name in PCE now that Tp resource is correctly
  recognized as a TpId instead of an Object (thanks to an improvement of
  leafref management in mdsal)

Remove few useless dependencies.

Disable lighty.io runtime for functional tests
(no lighty version compatible with phosphorus dependencies yet)

Adapt GNPy UT resource file.
