#84024 migrate Unimgr master to Neon-SR1

Donald Hunter

This change updates all the dependency versions to align with Neon-SR1

This seems to resurrect the Unimgr master branch to a working state. It is a prerequisite for:
  • merging up the stable/fluorine work
  • integrating apidoc explorer
  • experimenting with bgp-api on new MD-SAL
