Doesn't work without keycloak configuration file

Pravega benchmark doesn't work in unsecure mode.

commonsCLIVersion=1.3.1 commonsCSVVersion=1.5 commonsMathVersion=3.6.1 commonsIOVersion=1.3.2 pravegaVersion=0.8.0-2508.30406cf-SNAPSHOT pravegaKeycloakVersion=0.7.0-13.8cd1997-SNAPSHOT slf4jSimpleVersion=1.7.14

Trying to run benchmark: /opt/pravega-benchmark/bin/pravega-benchmark -controller tcp://pravega-pravega-controller.default.svc.cluster.local:9090 -scope scope-1 -enableConnectionPooling false -events 200000 -stream stream-s100-p1-XYZ -segments 48 -producers 5 -size 100 -time 60

And get:


ead=false, producerCount=5, consumerCount=0, segmentCount=48, segmentScaleKBps=0, segmentScaleEventsPerSecond=0, scaleFactor=2, events=200000, eventsPerSec=40000, eventsPerProducer=40000, eventsPerConsumer=0,

Caused by: io.pravega.keycloak.client.KeycloakConfigurationException: Unable to resolve a Keycloak client configuration for Pravega authentication purposes.

Use one of the following approaches to provide a client configuration (in Keycloak OIDC JSON format):
1. Use a builder method to set the path to a file.
2. Set the environment variable 'KEYCLOAK_SERVICE_ACCOUNT_FILE' to the path to a file.
3. Update the classpath to contain a resource named 'keycloak.json'.
