* Add support for contract upgrades
* Add interface for the upgraded contract to implement, which provides functionality for upgrading legacy states.
* Add shared upgrade command and verification code for it.
* Add DummyContractV2 to illustrate what an upgraded contract looks like.
* Add new functions to vault service to support upgrading state objects.
* Add contract upgrade flow
Add AnonymousParty superclass of Party in preparation for anonymising parties stored in
contract states.

Replaces the legacy name-only comparison in the vault service with a party comparison. `Party` now
has an equals method that only uses the owning key, and therefore this functions as expected.
Make FinalityFlow do more, and be used more consistently.
Add a new waitForLedgerCommit API that is intended to be used at the end of flows, or at any other point where a flow wants to wait for a transaction to finalise (but the finalisation flow is being done by someone else).
Update the docs a bit.
* Move merkle building extension functions on wire tx to WireTransaction class.
* Add timestamp, notary, transaction type and signers to wire transaction id calculation.
* Change construction of MerkleTree from duplicating last node on a given level to padding leaves' list with zero hash to size of the nearest power of 2 - so we always have a full binary tree.
The problem was that it was possible to construct 2 different transactions with the same ids. Trick worked for txs having number of leaves that were not power of 2.
* Update tear-offs documentation and diagrams to reflect changes in construction of Merkle trees - padding with zero hashes and including all WireTransaction fields in id computation.
* Change in filtering API of WireTransaction for partial Merkle trees calculation.
Instead of many filtering functions over a transaction only one needs to be provided.
Additional change to check and verification of FilteredTransaction.
* IRS demo change. Make filtering function a protected method of RatesFixFlow class.
Comment on situation when capturing too much scope and connected problems with checkpointing.
Change oracle and tear-offs documentation.
InMemoryNetworkMapCacheTest was not actually asserting that an expected exception was thrown, which
meant when earlier changes to the service changed the operation it wasn't caught. The service now
overwrites previous node if a new matching node is added, and this updates the test to follow that
design.
Change Party instances to be uniquely identified by the owning key, without taking into account name.
This requires that mock node key generation is reworked so that keys for services and the node itself
are distinct, otherwise the network map service cannot differentiate them.

This deprecates the existing composition clauses and adds new better named versions,
as well as changing 'AnyOf' to require at least one matching subclase (better matching
the name of the clause).
Add new functions for converting amounts to/from decimal representation. Also adds clarification that
the constructor which takes in a BigDecimal drops any fractional part.

The keys used to sign a command are tested for being a superset of the keys which own
the states, not for being an exact match (as the text previously suggested). This corrects
the message used if this requirement isn't met.

* Update notary change flow to support encumbrances.
Move encumbrance pointer from ContractState to TransactionState.
* Refactor & add new encumbrance tests
