I have developed a proxy service using ballerina language by referring the following [[1]](https://github.com/ballerina-platform/ballerina-lang/blob/master/tests/ballerina-integration-test/src/test/resources/proxy/proxyClient.bal) and [[2]](https://github.com/ballerina-platform/ballerina-lang/blob/master/tests/ballerina-integration-test/src/test/resources/http/httpservices/proxy_server.bal). It works perfectly fine. Now I want to run a load test via JMeter. That is JMeter should be configured in a such a way that the http request to a particular resource should be passed through the proxy service (In [1](https://github.com/ballerina-platform/ballerina-lang/blob/master/tests/ballerina-integration-test/src/test/resources/proxy/proxyClient.bal) mentioned above it is a client program and now I want to send the request via the JMeter). How to do it? How to configure the JMeter?
