* CORDA-1393: Install `onError()` handler for folding action
or else `ErrorNotImplementedAction` will be invoked which is never a good thing
* CORDA-1335: Improve exception handling in `cleanUpOnConnectionLoss()`
* CORDA-1335: Try to trick the logic to pretend we are running in HA mode to have a chance of re-connecting.
* CORDA-1416: Make `NodeMonitorModel` code react to proxy changing.
* CORDA-1416: Workaround `CordaRPCOps.equals()` calls when listener dispatching change.
* CORDA-1416: Increase re-try interval to allow enough time for server to come back online.
* CORDA-1355: Properly close RPC connection we are moving away from.
* CORDA-1355: Unsubscribe on Error to prevent propagation of it downstream.
* CORDA-1355: For downstream subscribers ignore errors properly. Thanka to @exfalso for the hint.
This fixes: Transaction Updates do not flow after re-connect
* CORDA-1355: Bugfix eliminate duplicating items on "Transactions" blotter after re-connect.
* CORDA-1355: Bugfix eliminate double counting on dashboards.
* CORDA-1355: Bugfix eliminate same parties in dropdowns.
* CORDA-1355: Stop using `SecureHash.randomSHA256()` for painting widget icon.
Instead use combined SHA hash such that icon represents the whole population of trades.
That way two transactions blotters can be compared by a single glimpse at corresponding icons.
Also minor refactoring.
* CORDA-1416: Make RPC re-connection faster/more robust.
* CORDA-1416: Properly announce thet Proxy may not be available during re-connect and prevent UI crashing.
* CORDA-1416: Disable UI until RPC proxy is available.
* CORDA-1416: Correct typo.
* CORDA-1416: Unit test fix.
* CORDA-1416: GUI cosmetic changes.
* CORDA-1416: Correct spaces.
* CORDA-1416: Remove un-necessary overrides in CordaRPCOpsWrapper.
* CORDA-1416: Switch from using `doOnError` to installing an error handler upon subscription.
Database transaction can be set to retry failure due to any exception with a cause or a nested cause of SQLException type.
Rationale: By the default transaction is retried only for SQLException. It may happen that SQL Exception is wrapped by Hibernate exception, allow to retry such cases if requested e.g. database.transaction(recoverableFailureTolerance = 3, recoverAnyNestedSQLException = true) { .... }
* Prepare node-api for determination.
* Disentangle Kryo and AMQP classes.
* Add version properties for fast-classpath-scanner, proton-j and snappy.
* Remove String.jvm extension function.
* Refactor Cordapp reference out of AMQP serialisers' primary constructors.
