Implement KVM in webui

This patchset adds the infrastructure to allow KVM sessions
through the webui. A websocket capable VNC/RFB connection
on the BMC is needed for KVM sessions.

To access, navigate to Server control -> KVM.

Tested: Ran obmc-ikvm on the BMC, added a KVM Handler to
        Phosphor Rest Server, and was able to establish a
        KVM session in the webui on a Witherspoon.
