[RFE] Add the ability to use a proxy server

[wy-ruby]

I can't connect directly to the vmware server. I need to use a layer of proxy in the middle. How can I configure this

[wy-ruby]

I was able to synchronize the data by modifying the code and using the proxy, but it failed to open vmware's virtual machine console
