Description

This is required for 0.19.0.

Upgrading into a "strict" replicated log backed registry can be done smoothly in two steps:

0.18.0 -> 0.19.0: this can go to a "non-strict", replicated log backed registry, which allows the replicated state to be bootstrapped from the current state of a cluster. The state would not be used to enforce any decisions. It will be "write-only" in this sense.

0.19.0 -> 0.20.0: this can move from a "non-strict" replicated log backed registry, to a "strict" one. This completes the upgrade, at which point reconciliation would be fully supported.
