CreatePod and MakePod only accepted an `isPrivileged` boolean, which made it impossible to write tests using those helpers which work in a default framework.Framework, because the default there is LevelRestricted. The simple boolean gets replaced with admissionapi.Level. Passing LevelRestricted does the same as calling e2epod.MixinRestrictedPodSecurity. Instead of explicitly passing a constant to these modified helpers, most tests get updated to pass f.NamespacePodSecurityLevel. This has the advantage that if that level gets lowered in the future, tests only need to be updated in one place. In some cases, helpers taking client+namespace+timeouts parameters get replaced with passing the Framework instance to get access to f.NamespacePodSecurityEnforceLevel. These helpers don't need separate parameters because in practice all they ever used where the values from the Framework instance.
