A transaction manager.
A transaction manager that is responsible for creating new transactions and keeping track of a current transaction. The transactions managed by this interface are assumed to be "composition" transactions (i.e. not yet committed or complete).
If multiple, disjoint TxnProvider objects are created, then it is assumed that their current transactions are likewise distinct.
