Connectors are partitioned by group instead of partition field.
Merge branch 'ip-controller' of https://github.com/vajanko/JDEECo into ip-controller
Connectors are partitioned by group.
IPTable renamed to IPRegister.
Added custom implementation of IPGossipStrategy for controller but only for debugging purpose.
IPController debug output removed. Fixed connector partitionBy field - "group" was already taken. Connector ensemble exchange only connectors information - all connectors must know about keys managed by the other connectors.
