Fix neo Suspendable to work with oceans ISuspendable Interface

[matthias-wende-sociomantic]

• implement suspended in Controllers.d Suspendable template class
• release swarm 6 d2 only (this will break current implementation of getAll request)
• enhance BatchRequestCore (Enhance BatchRequestCore (and implement node-side equivalent) #243)
• change all all nodes requests (e.g. getAll) to use BatchRequestCore (Rework GetAll to use batch-suspendable system from DMQ Consume / DLS GetRange dhtproto#38)
• deprecate handlePending in Controllers.d Suspendable template class
• deprecate SuspendableRequestCore
• release new dhtproto with working getAll request
