Description

Otherwise, we might end up with a situation where the mon believes an EC plugin is usable and creates such a pool, but it turns out that no OSD (or worse yet, only some of the osds) actually have that plugin. This probably should not be a thing where the mon distributes the plugin binary.

This should probably also include a versioning mechanism.

It happens on partial upgrades, when trying to create a pool that uses the lrc plugin. The OSD that have not been updated fail to load the lrc plugin because they do not have it and crash.

Does this draft patch goes in the right direction ? Or should the fix use a different path ?
