* chore(e2e): Namespace specific k8s resources for tests
Completes #576
- For ApiServer source: ClusteRole and ClusterRoleBinding name(s)
are now test-namespace specific. They are cleared in test's tearDown method.
- Use constant prefix as:
clusterRolePrefix = "apiserver-role-"
clusterRoleBindingPrefix = "apiserver-binding-"
- Use constant ServiceAccountName as:
testServiceAccount = "apiserver-sa"
- Rename methods and cleanup.
* Use correct format specifier for error as %v instead of %s
