NCM 7.3 moves to SWISv3

For a long time now, data and commands for Network Configuration Manager (NCM) were only available through SWISv2. Starting with NCM 7.3 - SolarWinds NCM 7.3 Release Candidate is Available! - NCM data and commands are now available through SWISv3, including the REST/JSON API. Scripts you have that target SWISv2 and leverage NCM entities should still work (though as always it is recommended to test any important scripts against new versions before upgrading production). You should switch these scripts to use SWISv3 when you can - future features may be added to SWISv3 only.
