Test Frontend Traffic
Given 100 pvc created.
And all pvcs deployed and detached.
When monitor traffic in frontend pod with nload.
apk add nload
nload
Then should not see a continuing large amount of traffic when there is no operation happening. The smaller spikes are mostly coming from event resources which possibly could be enhanced later (https://github.com/longhorn/longhorn/issues/2433).
