Better approach to finalisation of drools session... about hacep HOT 1 OPEN

Possible algorithm:

1. in the @DataRehashed PRE listener
   have a collection of primary keys for that node, C1
2. 1. in the @DataRehashed POST listener
      have a collection of primary keys for that node, C2

then call dispose on the drool sessions.

Or, get a look at https://raw.githubusercontent.com/anistor/infinispan/master/core/src/main/java/org/infinispan/notifications/cachelistener/event/DataRehashedEvent.java

that contains both the views before and after rehashing.

<+anistor> ugol_: both pre and post events contain to the before/after ConsistentHash objects. and method Address ConsistentHash.locatePrimary(Owner key) can be used to detect if a certain key is primary owned by current node
<+anistor> ugol_: EmbeddedCacheManager.getAddress() gives you your adress, so you can compare with what locatePrimary returns
