Add custom certificate authority, to run behing a corporate firewall

[slanglade]

Describe the enhancement you'd like to see
I'm running Monokle behind a corporate proxy (Global Protect) that transparently manage all connections. So everything certificates from internet seems to be signed by the proxy's own authority. This works if the tool you're using (browser, jvm etc.) is aware of this custom authority.
I need to have a way to add this CA to Monokle in order to be able to work with it. Currently, Monokle is totally useless.

Additional context
There is no way I can disable or change the proxy, this is a corporate choice and mandatory config.
