better proxy management to be able to execute tests behind a proxy

[lionnel]

Hi,

I'have isolated the initializeProxy to be able to set environment http.proxyUrl, http.proxyUser & http.proxyPassword to be able to pass local proxy.

Thank you for the suggestion, but is this really necessary? The JVM automatically picks the http.proxy* system properties to configure the proxy. We shouldn't have to redo the same work here.

Yes the JVM take account of proxy url (host and port).
But as far as I have checked it do not take account of the user/password part.
No pb if you do not merge the pr.
I'm trying to implement a verifier. As I work being an authenticate proxy, it's more to me to be sure not to push this part in the future pr.

The username/password properties should be used automatically, at least with Java 8:

Also if you work behind a proxy, you may want to try -Djava.net.useSystemProxies=true.
