Description of problem: We should upgrade from Liquibase 3.0.7 to 3.3.2. Additional info: Liquibase changelogs are here: http://blog.liquibase.org/category/announcement (From a quick read, I can't see any problems which should affect us) Previous updates were covered in bug 813165 and bug 1036435.
Pull request: https://github.com/zanata/zanata-server/pull/761
We need to test that existing databases are migrated without throwing any exceptions (like "change sets check sum 'abc' is now: 'xyz'").
