install tests (central, EA) are broken and failing

Checking these test jobs, I see they've been red for a while but no one has noticed.

https://dev-platform-jenkins.rhev-ci-vms.eng.rdu2.redhat.com/view/Devstudio/view/devstudio_installation_tests/job/jbosstools-install-grinder.install-tests.matrix_master/
https://dev-platform-jenkins.rhev-ci-vms.eng.rdu2.redhat.com/view/Devstudio/view/devstudio_installation_tests/job/jbosstools-install-p2director.install-tests.matrix_master/

So, a few things need to be done here:

a) make the tests pass
b) ensure emails are sent for unexpected failures to jbosstools-dev, nboldt, jmaury
