Replace event processing policy

Replace the entire event processing policy with the supplied ordered list of rules. If version is present in the request body it must match the current policy version, otherwise the request is rejected with status 409 and the body contains the current currentVersion. If version is omitted the policy is replaced unconditionally.

Each rule may be supplied either in the form produced by this API (object IDs and event codes as plain integers) or as a configuration export record (object/event references as objects carrying name and GUID); the latter form is resolved on import and any references that cannot be resolved are dropped, with details returned in the optional warnings field.
