Requery removal (#1276)

* Removed Requery object relational mapping usage (and associated schemas including node-schemas module)

* Fixed issues with NodeAttachmentService tests.
Cannot use JPA custom converters with Primary Key fields.
Hibernate entities require explicit call to flush() to persist to disk.

* Removed redundant requery converters (equivalents not even required in Hibernate).

* Removed remaining gradle requery dependency definitions.

* Fixed broken tests.

* Fixes for failing NodeVaultService tests:
- Dynamic SQL updates (in soft locking code)
- Explicit request by session to participate in transaction (causing "TransactionRequiredException" Executing an update/delete query)
- Explicit flush() required to persist to disk

* Updated changelog.
Fixed compiler warning.

* Fixed WHERE clause AND/OR condition.
Enforced immediate data visibility through transaction commit.

* Final fixes to address failing tests.

* Deferred all hibernate session/txn management to DatabaseTransactionManager.

* Fixed transaction boundaries in failing Cash tests.

* Fixes to address failing tests (transaction boundaries, merge detached object, config clean-up).

* Final adjustment to transaction boundaries in JUnit tests.

* Refactored AttachmentSchemaV1 into NodeAttachmentService itself and referenced from NodeServicesV1.

* Refactored HSQL UPDATE statements to use CriteriaUpdate API.

* Updated all criteria API getters to reference attribute names by type.

* Remove redundant VaultSchema entity name (required when previously using HSQL UPDATE syntax)

* Fix compiler warnings.

* Minor changes following rebase from master.

* Fixed suppress warning type.
