Update install.sh

[fla77ire]

moved growpart to the beginning, changed partition value to 3, and added subscription-manager refresh to bastion-deploy.sh

With having growpart at the end of the install, root became 100% full prior to finishing openshift_install.

Also kept running into "The requested URL returned error: 404 Not Found" on the repos, so by adding the refresh it took care of that.
