[Hawkular-dev] Separate maven build of Inventory UI

Hi, While I'm really glad that inventory has an embedded UI, very helpful while testing and debugging, it's a bit sad that it involves nodejs/npm build triggered during the maven build of hawkular-commons (build time is more than tripled). For Hawkular Metrics UI we use a separate repo (hawkular-ui) for the build: all npm/nodejs build stuff happens there. On hawkular-metrics side, before preparing the WAR, the webapp is pulled using maven SCM plugin. What do you think, can we have a similar process here? (I'd volunteer to do it)
