Vault Query Service JPA implementation (#840)

* Vault Query Service API implementation using JPA Hibernate

Added queryBy(QueryCriteria) Vault API and Junit tests.

Minor cosmetic API changes following rebase.

Fixes following rebase from master

Upgraded to requery 1.3.1

WIP - removed 'latestOnly' from LinearStateQueryCriteria

WIP - CommercialSchemas V2, V3, V4 testing

WIP - sort out generics handling.

WIP - most general queries completed.

WIP - join queries, contractStateType derivation

WIP - refactoring Requery

WIP - refactored VaultService to extract a VaultQueryService interface (and associated Requery implementation).

WIP - HibernateVaultQuery implementation

WIP - Re-structured all Schema definitions (requery/jpa) and make Hibernate Config reusable.

WIP - Multi-version schema testing, hibernate query testing.

WIP - Custom Criteria and Fungible Criteria impl & testing.

WIP - Kotlin Comparable Generics error

WIP - Party queries all working now

WIP - All VaultQueryTests now working (refactored for AND / OR composition)

WIP - added schema registration in CordaPluginRegistry to enable custom vault queries on arbitrary schemas.

WIP - added new default Sort NULL order to be NONE + added lots more tests for Logical Operator testing.

Mostly identity fixes following rebase from master.

Exception handling and public API cleanup in prep for PR.

Additional tests for Logical Operators; additional tests for NULLS sort ordering; additional logging;

Additional parser to handle Nullable attribute values; added Unary and Collection logical expression handlers

Lots of cleanup: participants; trackBy interfaces; additional fungible tests; parser cleanup and improved support for Java

Removed all traces of Requery implementation.

Further minor cleanup and Junit test fix.

Final identity and schema related identity clean-up.

Revert unrelated changes.

PR review updates: blank lines, isRelevant.

Fixed wiring of updatesPublisher for dynamic trackBy queries.

PR review changes: multi-versioned schema samples and associated dummy contracts moved to test packages.

Fixed problem with sorted queries (not specifying any filterable criteria).

PR review: minor updates to address RP comments.

Typesafe custom query criteria

Cleanup: remove redundant tests.

Further clean-up and make all Java test work successfully.

Remove debugging print statements.

Rebased from master - changes required due to DealState module change.

fixed broken assertion caused by DealState ordering change (different package)

Fixed transaction demarcation issue causing "java.lang.IllegalStateException: Was not expecting to find existing database transaction on current strand"

trackBy() now filters on ContractType and StateStatus (CONSUMED, UNCONSUMED, ALL)

Added tests to exercise RPCOps trackBy and queryBy (RPC smoke test and CordaRPCOps)

Added additional @CordaSerializable annotations.

Updated documentation and referenced sample code.

Added deprecation annotations.

Re-added missing deprecation annotation.

Hibernate debug logging is now configurable and disabled by default.

Introduced common Sort attributes based on the node schemas.

Completely removed NULL_HANDLING sort parameter as this is not supported in JPA.

Revisited and fixed usage of @CordaSerializable.

* Minor fix following rebase from master.

* Remove blank line as per RP PR feedback request.

* Minor Java documentation and example clean-up.

* Disable BFT Notary Service tests.
