It's time for This Week in OpenNMS!

Last week worked on wrapping up various things targeted to Horizon 23,
plus we continued work on new features relating to integration,
refactoring of Enlinkd, the Helm UI, and more.

      o Markus worked on removing the NCS integration code.

        protocols on a single UDP port.
      o Jesse made some small enhancements to OCE startup.
