Add ability to proxy VNC port

[vania-pooh]

Should be able to proxy vnc port by session ID like the following:

/vnc/<uuid>

The request like this...

GET /vnc

... should return a list of currently available videos.

@vania-pooh would video files be available for pulling out from containers (or mapped folders)?.. or it'd be just a live streaming via selenoid-ui?

@sskorol this is one is about streaming only to Selenoid UI. Regarding video - this is a more complicated task. In my current understanding we can't capture video directly from VNC. In order to capture video we need to use something like this. The method described in the article requires installing ffmpeg and using x11grab driver. Installing all this software to every container will dramatically increase their size. So if you know a better way to capture video (e.g. directly from VNC) - please tell us.

So unless you know very simple way to capture video from VNC, video feature will be one of the next.

@vania-pooh personally I have used ffmpeg for video recording in containers. It was chosen for Allure compatibility (as it supports only html5-video formats at moment).
