CAMEL-20113: camel/tests consolidating (#12778)

apache.camel.itest.jms
-JMSTransactionIsTransactedRedeliveredTest - almost the same case is tested in org.apache.camel.component.jms.tx.JMSTransactionIsTransactedRedeliveredTest, so this test is deleted.
org.apache.camel.itest.nettyhttp
-NettyHttpClientChunkedResponseTest - created similar test in netty-http component, with chunked response but without jetty. Original test was deleted.
