L3 - Default Description
AT:
- all tests use h2 database 1.4.x
- supported environments are updated
- Remove the ignore condition for H2 database in "org/camunda/bpm/qa/upgrade/authorization/AuthorizationTest.java" after upgrade
Motivation:
- there is a bug in H2 1.3 such that some authorization checks seem to not work (e.g. failed tests org/camunda/bpm/qa/upgrade/authorization/AuthorizationTest.java in the instance migration test suite)
- there seem to be issues with H2 1.3 and parallel access that appear to be in the new storage engine 1.4 uses
