Modified core to support drop and schema-sqlf.sql but leverages derby syntax outside of connection string.

Modified *.properties file to add additional property "batch.isolationlevel=ISOLATION_SERIALIZABLE
because batch-sqlf.properties needs batch.isolationlevel=ISOLATION_READ_COMMITTED.
Added corresponding sqlf properties and sqlf files.
Modified simple-job-launcher-context.xml to support the p:isolationLevelForCreate="${batch.isolationlevel}"
