… (antrea-io#7741) The FlowAggregator SecureConnection tests were flaky. Flows took a long time to arrive in the FlowAggregator. When they did, it was only 1 flow instead of the expected 3. The Delta count and Total count were always equal due to the FlowExporter buffering the flow data before sending it. This was caused by the fact that FlowAggregator was redeployed for each subtest. The Agent was slow to reconnect to the freshly deployed FlowAggregator. Thus, the FlowExporter didn't match the expected timings of the tests. The test setup was updated to check FlowAggregator metrics after each redeployment. This ensures the FlowExporter has reconnected to the new FlowAggregator before testing.
