[Pulp-dev] Pulpcore RC3 Updates and Planning

The RC3 has several items on its blockers list [0], so we will not be
releasing on Monday the 24th. The plan is to release when either the
blockers are all resolved or on Friday the 28th, whichever comes first. Any
remaining blockers will go onto an RC4 blockers list.

# Plugin Updates Required
One new issue #4990 [1] discussed today during open floor will require a
small-but-necessary change for any plugin that implements on-demand
policy='streamed' or policy='on_demand'. Specifically you'll need to
override the 'policy' field on your detail Remote's serializer to allow for
those values. #4990 will include these docs (likely done Mon/Tues), but I
wanted to give a heads up. Without this change RC3 will break lazy for your
users because they won't be able to make the Remote.

Any feedback or ideas are welcome (either on list or off).
