Bug Description

For a long time, noVNC set the token inside a cookie so that when the /websockify request came in, we had it in the cookies and we could look it up from there and return the correct host.

However, since the following commit, they've removed this behavior

https://github.com/novnc/noVNC/commit/51f9f0098d306bbc67cc8e02ae547921b6f6585c#diff-1d6838e3812778e95699b90d530543a1L173

This means that we're unable to use latest noVNC with Nova. There is a really gross workaround of using the 'path' override in the URL for something like this

http://foo/vnc_lite.html?path=?token=foo

That feels pretty lame to me and it will have all deployment tools change their settings. Also, this wasn't caught in CI because we deploy novnc from packages.

    Use non-broken commit for NoVNC

    NoVNC shipped a change that broke the entire Nova integration,
    this patch reverts to the change *just* before it in order to
    be able to ship a working NoVNC.

    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 note about needing noVNC >= v1.1.0 with using ESX

    As discussed on the following review:

      https://review.opendev.org/674916

    this adds a note indicating that the version of noVNC needs to be at
    least v1.1.0 in order for the nova-novncproxy to work with ESX/ESXi
    hypervisors.
