MODE-2028 Updated the EAP kit to 6.1.1.GA

For validating this PR, make sure that:

* if you're using a local `settings.xml` you update your EAP repo to: http://maven.repository.redhat.com/techpreview/eap6/6.1.1/maven-repository
* you run the `/bin/install-eap.sh` script passing in the `jboss-eap-6.1.1.zip`. The latter is not available atm via `jboss.org`, but is available via the client portal.

The updated kit is backwards compatible with EAP 6.1.0, so if for some reason you can't get `jboss-eap-6.1.1.zip`, just run the script passing in `jboss-eap-6.1.0.zip`
