Documentation - Provide information how to use deploy.sh script to deploy RHAMT into Openshift

In [1] is mentioned that deploy.sh will provide URL to deployed RHAMT on Openshift but it's not described how it should be used. There is only how to click it in Openshift UI which is basically what deploy.sh script does.

Script is located in ...rhamt-web-distribution-4.3.1.Final/openshift/deploy.sh and there is also README.md how to use it but official doc does not mention it.
