Mohammed Naser 9606c80402 Add 'path' query parameter to console access url
Starting in noVNC v1.1.0, the token query parameter is no longer
forwarded via cookie [1]. We must instead use the 'path' query
parameter to pass the token through to the websocketproxy [2].
This means that if someone deploys noVNC v1.1.0, VNC consoles will
break in nova because the code is relying on the cookie functionality
that v1.1.0 removed.

This modifies the ConsoleAuthToken.access_url property to include the
'path' query parameter as part of the returned access_url that the
client will use to call the console proxy service.

This change is backward compatible with noVNC < v1.1.0. The 'path' query
parameter is a long supported feature in noVNC.

Add support for noVNC >= v1.1.0 for VNC consoles. Prior to this fix, VNC
console token validation always failed regardless of actual token validity
with noVNC >= v1.1.0. See
