Go version < 1.16

To check leaf: put mode = 1 in hub cluster and 2 in leaf.

Check performance with different replica value in cluster

Examine number of threads (services) producers or consumer.

Positive test.

1. NATS_STREAM_USER create stream and consumer with REPLICAS num.

2. NATS_USER send message PUSH_NUM times

3. NATS_USER tries to reed them.
