tag ingress streams as camera or screen share when no transcoding is specified

[slabajo]

Currently, when we setup an ingress stream as WHIP source with not transcoding to avoid wasting server resources. But in that case the ingress interface does not allow us to tag the tracks in the ingress as screenshare or screenshare audio.

As application manage differently main video from screenshare, there are some use cases where it is needed to tag some ingress streams as screenshare.

This will require a small API change for setting up WHIP with bypass_transcoding.

Ok, don't worry, it was a suggestion to provide a more complete service. AS I said in another issue we needed to implement our own ingress where we manage this feature
