Add a user preference for console type (vnc vs spice)

[Rafi Khardalian]

Currently Horizon makes an attempt to obtain a VNC console and will fallback to Spice. While this is a reasonable default, it would be really nice for users to be able to select their preference. Perhaps something along the lines of "Auto (Default)", which is the current behavior, Spice and VNC, the latter two being forced if set. This will allow users to switch console modes themselves if they have any issues.

Well, I think it's a viable request and will improve user experience. Thanks.

I don't think end users should be given this choice, but it should be configured based on 1) a setting in local_settings.py that an administrator controls, and 2) browser capabilities.
