examples: update the examples with new lazy scheduling flags

Browse source 
The src can listen to RequestProcess commands and so gets the
node.supports-request = 1 property.

The play-pull example can both be a driver that listens to
RequestProcess or a lazy driver so set this in properties as well.
We can now remove the priority.driver property because automatic
priority selection will make us a driver or not.

With this change, video-src to video-play-pull will use lazy scheduling
with play-pull as the driver. video-play-pull to v4l2src will use
normal scheduling and video-src to video-play will also use normal
scheduling.
