DDF-615 Add Install Profile Step to Installer

This will add Install Profile step to the install.  Web Service needed to be added to get all install profile features from the "install-profiles" project (SEE https://github.com/codice/ddf/pull/9).
Just tried integrating the Karaf Feature Service has the features most of the feature data I need.  However it doesn't appear like it includes the "description" attribute from the features.
