* The ShardTransaction Actor represents a remote transaction

* The ShardTransaction Actor delegates all actions to DOMDataReadWriteTransaction

* Even though the DOMStore and the DOMStoreTransactionChain implement multiple types of transactions
* the ShardTransaction Actor only works with read-write transactions. This is just to keep the logic simple. At this
* time there are no known advantages for creating a read-only or write-only transaction which may change over time
