This component supports the http.proxyHost system property (or proxy_host environment variable) for configuring a proxy server, but it is not honored in WebSocket mode. By plumbing this through to Tyrus we can get Tyrus to respect the proxy settings the same way non-WebSocket mode does. Similarly we can plumb through the value of -proxyCredentials to Tyrus if the user needs to pass in a Proxy-Authorization header (like we do in non-WebSocket mode). We do this only for HTTP to match the non-WebSocket mode.

Testing done

Set up a Squid proxy that required authentication and verified that I could connect through it using:

java -Dhttp.proxyHost=${HOSTNAME} -Dhttp.proxyPort=3128 -jar target/remoting-999999-SNAPSHOT.jar -url ${JENKINS_URL} -secret ${SECRET} -name test -webSocket -proxyCredentials ${USERNAME}:${PASSWORD}

String proxyHost = System.getProperty("http.proxyHost", System.getenv("proxy_host"));
String proxyPort = System.getProperty("http.proxyPort");
if (proxyHost != null && "http".equals(hudsonUrl.getProtocol()) && NoProxyEvaluator.shouldProxy(hudsonUrl.getHost())) {
