added Performance label

assigned to @joseha

Implemented in feature/100/gpu. There seems to be an issue with libSGM.

I believe it is resolved but must check in lab with real data. Issue was not libsgm but that it was constructed in setMask function and not grab. Also, depth output was in mm not meters so I also adjusted scale. Seems good.
