Implements range scan for keys in windowed and session stores
Modifies caching session and windowed stores to use segmented cache keys.
Cache keys are internally prefixed with their segment id to ensure key ordering in the cache matches the ordering in the underlying store for keys spread across multiple segments.
This should also result in fewer cache keys getting scanned for queries spanning only some segments.

Add new broker config, `group.initial.rebalance.delay.ms`, with a default of 3 seconds.
When a consumer creates a new group, set the group's state to InitialRebalance and delay the rebalance until `min(group.initial.rebalance.delay.ms, rebalanceTimeout)`. As other members join the group further delay the rebalance by `min(group.initial.rebalance.delay.ms, remainingRebalanceTimeout)`. Once `rebalanceTimeout` is hit or no new members join the group within the delay, complete the rebalance.

This is the implementation of KIP-114: KTable state stores and improved semantics:
- Allow for decoupling between querying and materialisation
- consistent APIs, overloads with queryableName and without
- depreciated several KTable calls
- new unit and integration tests
In this implementation, state stores are materialized if the user desires them to be queryable. In subsequent versions we can offer a second option, to have a view-like state store. The tradeoff then would be between storage space (materialize) and re-computation (view). That tradeoff can be exploited by later query optimizers.

Closes#2832 from enothereska/KAFKA-5045-ktable
The descendingSubsequence is a misnomer. The linked list is actually arranged so that the lowest timestamp is first and larger timestamps are added to the end, therefore renamed to ascendingSubsequence.
The minElem variable was also misnamed. It's actually the current maximum element as it's taken from the end of the list.
Added comment to get() to make it clear it's returning the lowest timestamp.
