Please also add README.md in https://github.com/open-edge-platform/dlstreamer/tree/main/samples/gstreamer/python/concurrent

This is the only non-documented in github, README.md can be very short here - just redirect to other article in documentation... but if someone will search through samples they will have no clue what is this sample code about.

Could we change the file name to something more informative? Maybe "dlstreamer-deepstream-coexistence.md" would fit?
