-----------------------------------------------------------

To know what's actually included in the RPM (after this PR is applied): {code}
rpm -e rh-eclipse46-devstudio 
rpm -i rh-eclipse46-devstudio-1.0-1.el7.noarch.rpm
rpm -q --provides rh-eclipse46-devstudio | tee /tmp/rh-eclipse46-devstudio.provides.list.01
{code} --> [^rh-eclipse46-devstudio.provides.list.01]

Unfortunately even with this change, the RPM is only down to 447M from 460M. 

This is because p2 resolves dependencies transitively in the update site mirror used for the RPM, and if devstduio includes org.jboss.tools.openshift.egit.integration.feature, it will depend on egit, and thus pull in that feature to the mirror.

So... we need a way to make the mirror less greedy.
