PDI-7516 Specifying large limit in Cassandra input step causes timeout errors
PDI-8731 - Cassandra SSTable Output (bulkloader) step does not work with Cassandra 1.1.x

Add missing dependencies
Add support for cassandra 2.x
Split writer into CQL2 and CQL3 specific ones
Try preventing JVM from exit in case issues with cassandra config
Fixes for CQL2 writer:
 - read partitioner from config, use Murmur3Partitioner by default
 - store date as longs
