Initial proxy configuration

[snakebyte91]

It is not possible the set the proxy configuration in the UI or with the API on the first start. The server is not getting ready and connections are answered with connection refused.

Workaround is to set iq_server.javaOpts to "-Dhttps.proxyHost=my-proxy-server -Dhttps.proxyPort=3128 -Dhttps.nonProxyHosts=\"localhost|127.0.0.1\"". Configure the proxy afterwards with the API and then remove the attribute iq_server.javaOpts.
