Merged HEAD-BUG-FIX (5.0/Cloud) to HEAD (4.3/Cloud)

Browse Source 
71594: Merged V4.2-BUG-FIX (4.2.3) to HEAD-BUG-FIX (4.3/Cloud)
      70332: Merged V4.1-BUG-FIX (4.1.9) to V4.2-BUG-FIX (4.2.3)
         70292: Merged DEV to V4.1-BUG-FIX (4.1.9)
            60077: Created branch for MNT-10067 work.
            60101: MNT-10067: first commit of a generic SQL script runner.
            Very rough and ready extraction of SchemaBootstrap SQL script execution functionality. Will serve as the basis for the implementation of MNT-10067.
            60147: MNT-10067: added tests for "dialect" placeholder resolution, including overriding of dialects.
            60180: MNT-10067: exception thrown when unable to find SQL script to execute
            60187: MNT-10067: renamed ScriptExecutor to ScriptExecutorImpl to make way for an interface definition.
            60188: MNT-10067: introduced a ScriptExecutor interface.
            60189: MNT-10067: renamed ScriptExecutorTest
            60190: MNT-10067: added ScriptExecutorImplIntegrationTest to repo test suite.
            60194: MNT-10067: a very simple initial implementation of a SQL script runner capable of running multiple scripts in a given
            directory.
            60195: MNT-10067: added integration test for ScriptBundleExecutorImpl.
            60196: MNT-10067: moved ScriptBundleExecutorImplTest to correct source tree.
            60197: MNT-10067: added ScriptBundleExecutorImplIntegrationTest to repo test suite.
            60263: MNT-10067: ScriptBundleExecutor(Impl) now stops executing the main batch of scripts upon failure and runs a post-script.
            60459: MNT-10067: minor change to test data to avoid implying that ScriptBundleExecutor.exec(String, String...) has an always-run
            final script.
            60482: MNT-10067: added integration test for ScriptBundleExecutor.execWithPostScript()
            60483: MNT-10067: committed missing files from r60482
            60488: MNT-10067: set appropriate log levels for log4j
            60620: MNT-10067: added alf_props_xxx clean-up script.
            60623: MNT-10067: minor tidy up of ScriptExecutorImpl (tidy imports, group fields at top of class)
            60625: MNT-10067: further tidy up ScriptExecutorImpl (removed redundant constants, made externally unused public constant private)
            60629: MNT-10067: fix tests broken by introduction of scriptExecutor bean in production code.
            60662: MNT-10067: added tests to check deletion of doubles, serializables and dates.
            61378: MNT-10067 : Cleanup alf_prop_XXX data
            Added MySQL, Oracle DB, MS SQL Server and IBM DB2 scripts.
            63371: MNT-10067: removed the vacuum and analyze statements from the postgresql script.
            63372: MNT-10067: replaced begin and commit statements (PostgreSQL script only) with --BEGIN TXN and --END TXN, handled by the
            script executor.
            63568: MNT-10067 : Cleanup alf_prop_XXX data
            Added start and end transaction marks to the scripts.
            64115: MNT-10067: added Quartz job that by default doesn't fire until 2099 and can be manually invoked over JMX.
            64223: MNT-10067: improved testing for AuditDAOTest and added PropertyValueDAOTest
            64685: MNT-10067: added AttributeServiceTest
            65796: MNT-10067 : Cleanup alf_prop_XXX data
            Implemented a performance test.
            65983: MNT-10067 : Cleanup alf_prop_XXX data
            Reworked the MySQL script.
            Added time measurements for entry creation.
            66116: MNT-10067 : Cleanup alf_prop_XXX data
            For MySQL:
            1) Renamed temp tables.
            2) Split the script into execution and cleanup of temp tables parts.
            67023: MNT-10067 : Cleanup alf_prop_XXX data
            Modified MySQL script to skip null values from alf_prop_unique_ctx.prop1_id.

            Added additional cleanup before main script execution.
            68710: MNT-10067 : Cleanup alf_prop_XXX data
            Added batch logging.
            Moved clearCaches() statement in PropertyValueDAOImpl.cleanupUnusedValues() to finally block.
