chore: cleanup

1. Renamed form UfrmNGrokOptions to UfrmServerOptions
2. Renamed kmdev-server to just plain server
3. Tidied up npm versioning to use VERSION_WITH_TAG

This last point should help avoid confusion as now only CI release
builds will ever generate a package.json with a.b.c, a.b.c-alpha or
a.b.c-beta. Local and test builds will always have the corresponding
-test or -local environment appended. This also helps avoid issues if
we accidentally publish an incorrect version.
