Adapted crank.txt files to new config command.
Fixed Minion to not allow 0 health checks (which sometimes happens if the configuration didn't make it before the health check service tried to execute it).
Reverted crank files back to o.a.s.launchpad.karaf/0.1.1-SNAPSHOT from o.a.s.launchpad.impl/0.0.1-SNAPSHOT after SLING-3529 was closed as WONTFIX.
Updated crank files to use variables.
Updated Vagrant scenario to start instances with Crankstart instead of Launchpad standalone.
