> The MessageStore (and DurableConfigurationStore) implementations are currently stateful.
They own the recovery process and have special rules around some states (in some states updates
are ignored).  This is overly complicated.  Currently all store implementations need to code
these rules. This is poor division of responsibilities and this presents a barrier to users
wishing to produce their own store implementations.
> This change will simplify the responsibilities of the store:
> * introduce simpler lifecycle methods i.e. open/close
> * simpler state concept, the store is either open or not
> * visit methods for retrieving data from the store.
