Fix integration tests

[erikbra]

• Maxparallel 1
• Less tests - takes less time, while debugging
• Running the test DLLs directly to better discover errors
• Try running with multiple postgres'es
• Added test report step
• Try turning off parallelization
• Fixed a couple of errors
• Enable all DBs, change name of test report
• More verbose debug message when trying to connect to non-existing db
• Set timeout on the job
• Working on Oracle
• Added Drop of all test DBs after running test
• Timeout 12 mins
• Separate test steps in CmdLine and DLLs
• normalize line endings in error message before checking
• Some Oracle fixes
• Run 'build failure' steps on not success (not working)
• Smink v 0.4.0
• Disable Azure tests for now (too brittle, and too expensive)
• Add Docker based tests for all DBs (only form ubuntu client, though. But, better than nothing)
