SLING-3009, SLING-3029 and SLING-3030:
 SLING-3009 : add support for deploying osgi bundles via the configured sling launchpad server
                   there are two modes: locally (via SLING-3019) and via mvn sling:install
 SLING-3029 : allow to connect to the sling launchpad server both in 'run' and in 'debug' mode. 'debug' mode sets all the necessary settings incl the source code lookup
  SLING-3030 : until we have SLING-2989 make sure we have at least one way of deploying a content-bundle to a configured sling-launchpad. the chosen solution for that is to use 'mvn content-package:intsall' - while this is certainly too slow at the moment, it is still a usable temporary solution
