Detailed Description

Invariants: Loan brokers are internally consistent.

1. If LoanBroker.OwnerCount = 0 the DirectoryNode will have at most one node (the root), which will only hold entries for RippleState or MPToken objects.
2. Under featureLendingProtocolV1_1, an ltLOAN_BROKER may only be deleted by a ttLOAN_BROKER_DELETE transaction, and only when its pre-state OwnerCount is zero and its pre-state DebtTotal rounds to zero at the vault's AssetsTotal scale, as LoanBrokerDelete::preclaim requires.
3. At most one ltLOAN_BROKER may be deleted in a single transaction.
