Context which is needed by a map service.
Shared instances, configurations of all maps can be reached over this context.
Also this context provides some support methods which are used in map operations and {@link RecordStore} implementations.For example all {@link com.hazelcast.map.PartitionContainer} and {@link com.hazelcast.map.MapContainer} instancescan also be reached by using this interface.
It is also responsible for providing methods which are used by lower layers of Hazelcast and exposed on {@link com.hazelcast.map.MapService}.
