> Once overall install fails, allow the user can go back to any step in the Install Wizard.
> Current navigation lockdowns should still apply, such as:
> * While deploy is in progress (both install and start phases), the user cannot navigate
to any other step.
> * Once deploy succeeds, the user can proceed to Step 10 but cannot go back to a previous
step.
> We need to invoke DELETE on the existing cluster, if any. This should be part of the
deploy prep (upon clicking "Deploy" in Step 8), to be executed first.
> Notes:
> * Since the user can go all the way back to Step 1 and change the cluster name, we need
to make sure that we are deleting the existing cluster with the correct name.
> * Note that the changes apply only to Install Wizard; Add Hosts navigation should not
change.
