Set no_proxy in the okhttp builder in case the proxy_url is null

[jkhelil]

Description

When the proxy properties are set (http.proxy, no.proxy...) and the master host should not go through the proxy, okhttp is still tunneling over the proxy, we should disable the proxy in case where the master url should not go through the proxy
it is working also when the proxy.url is not found
