Migrating plugins to killbill 0.24.0 wiremock

[Roger Parkinson]

I have a plugin that uses wiremock and when migrating it I run into problems with dependencies. The wiremock version managed by killbill-oss-parent is 2.27.2 (the latest non-beta version) . When I run it I get this:

java.lang.NoSuchMethodError: 'void org.eclipse.jetty.server.NetworkTrafficServerConnector.addNetworkTrafficListener(org.eclipse.jetty.io.NetworkTrafficListener)'

So it looks like a mismatch between the wiremock version and the version of jetty wiremock wants to use. But I did solve this by forcing the wiremock to an earlier version (1.58) which works for me. The problem seems to be that wiremock 2.27.2 has inconsistent dependencies.

I did try a later version of wiremock (V3) but it is still in beta and it I get errors from the maven plugin that enforces minimum/maximum versions.
