Unit test in client module fails on some systems because it runs too fast (1.6.x)

PR: #1951

The com.networknt.client.Http2ClientPoolTest.testResponseTime fails in the client module since the test is able to complete in less than 1 ms on some systems. Since the speed (in ms) is casted to a long, this sub-1ms runtime is converted to 0L, which causes the following check to fail:

light-4j/client/src/test/java/com/networknt/client/Http2ClientTest.java

Line 528 in 52548c5

Assert.assertTrue(ar.result().getResponseTime() > 0);

Solution is to change this line of code to:

Assert.assertTrue(ar.result().getResponseTime() >= 0);

In the same module, an identical check is made in the Http2ClientPoolTest.testResponseTime() unit test. This is also fixed to allow a time of 0L.
