Pulp - Story #3693: Lazy for Pulp3
README has example of policy='cache_only' but no info about the streamer
It's no longer possible to copy-paste readme for the case when the streamer is not running, at the same time README doesn't refer to info about the streamer.
I suggest either to have immediate policy covered in README or to have all policies covered but also provided information about the streamer. E.g. "To use this policy, streamer service should be running, read how to configure it here."
