Correct behaviour of anonymousToParty() in identity API; it previously presumed any Party was a well known
identity, now it tries to look up the well known identity irrespective of whether it's been given a full
party or not.
* flows: Add StackDump, debugStackDump, test (doesnt work)
* Polishing Quasar dump feature, extending it with persisting to a file, adding integration tests
* Addressing review comments
* Addressing 2nd round of review comments
* Refactoring implementation according to Shams suggestion
* Reverting changes and restoring the feature to be the part of the core API
* Switching to ServiceLoader
*Remove dummy public keys in preference for EdDSA keys generated from fixed entropy sources, as a more accurate reflection of real uses. Also eliminates a serialization format issue with dummy keys which would have to be resolved otherwise.
* Remove deprecated 'by' keyword from contracts DSL
* Remove deprecated parts of CordaPluginRegistry
* Merge identity registration of well known and confidential identities
* Move verification logic into PartyAndCertificate from IdentityService
* Add note about why PartyAndCertificate exists
checkSignaturesAreValid() calls TransactionSignature.verify(), which throws InvalidKeyException but
checkSignaturesAreValid() did not indicate it could throw InvalidKeyException.
* Remove hard coded commercial paper issuer from trader demo
* Issue commercial paper from the Bank of Corda node, as per previous hard-coded issuer name
* Issue cash from the Bank of Corda node rather than in response to the buyer node requesting issuance
* Added JPA AbstractParty converter (using IdentityService to resolve anonymous parties).
* Use partyFromX500Name. Add meaningful exception messages.
* AutoApply the JPA AbstractParty converter.
* Entity attribute still needs the Convert annotation.
* Fix incorrect registration of custom attribute converter.
* Deal with non-resolvable anonymous parties (eg. store as null and ignore)
* Updates following PR review feedback.
* Added documentation.
* Added entry to changelog.
* Added code documentation as per RN PR feedback request.
* Updates required following rebase from master.
* Renamed converter for clarity.
