Chart name is different for chart pushed to OpenShift

[jfdenise]

This issue appeared with XP5. In our released EAP XP5, the chart is named eap-xp5, it needs to be named redhat-eap-xp5.

As a short term solution for the release, In the redhat-eap-xp5-1.0.0.tgz pushed to the https://github.com/openshift-helm-charts/charts repo, I did the following changes:

• changed the directory structure inside the tgz from ./eap-xp5-1.0.0/eap-xp5/* to ./redhat-eap-xp5/*
• In Chart.yaml, changed the name from eap-xp5 to redhat-eap-xp5

In addition the chart verifier reports some errors that need to be investigated.
