e2e-test / openSUSE / amazon instances: missing package hub repositories

[klihub]

Describe the bug
On openSUSE on amazon instances the package hub repository is not enabled by default. This prevents the scripts from successfully bootstrapping a working cluster. Also, after manually enabling the repository and rerunning the scripts, the failed step of pulling in the necessary packages is not retried.

Expected behavior
Successful bootstrapping of a working K8s cluster on amazon instances running openSUSE.

To Reproduce
Run vm=mytestvm distro=opensuse VM_IP=$mytestvm_ADDRESS VM_SSH_USER=ec2-user test/e2e/run.sh to try bootstrapping a cluster and running some tests.

Making sure the package hub repo is enabled reportedly fixes this problem.

Additionally, it might be an idea worth considering to add a flag akin to reinstall_crirm & co and allow users forcing the bootstrapping process to be retried all the way from the beginning (pulling in the necessary packages). Now rerunning the script after a failure with package hub enabled does not retry that failed step.
