Title: Setting cassandra transaction timestamp

CassandraTransaction can be initialized with a timestamp.
StoreManager allows to create transaction with
StoreManager.beginTransaction(Long timestamp).
The only real implementations are provided for
Cassandra store managers.

When applying changes to the graph, the new transaction
has to be created manually, rather than auto-started.
