[Rolling upgrade] Create and deploy contract for synchronizing versions
In order to synchronise EN version switchover, as described in a design document height to version map is to be stored as part of service account, and thus available to every node in an uniform manner.
It should be designed with https://app.zenhub.com/workspace/o/onflow/flow-go/issues/3047
This includes first actually defining and designing the best approach to the problem, and then implementing it.
