cherry-pick(release-v1.3.x): Create cluster-wide resources only once in performance test (#1308)

[pmacik]

Signed-off-by: Pavel Macík [email protected]

Currently, the performance as part of simulated users actions it applies YAML files with resources. Those resources contain also the cluster-wide resources such as ClusterRole or ClusterWorkloadResourceMapping.

Since that YAML is applied by each of the simulated users those cluster-wide resources are constantly being "updated" by which sometimes causes the "the object has been modified; please apply your changes to the latest version and try again" error that fails the test.

That causes the performance testing jobs to be flaky.

Changes

This PR fixes the situation by applying the cluster-wide resources only once instead of for each for each iteration.
