Previously we used to have tests scattered around, so let's put
them under one directory to make things more clear.
Now under top level test directory we have directories:
audio - objective audio quality tests
used to be under test/
qa - qa tests run by the CI
new test component in soft repo
topology - topology test file generation
used to be under topology/tests
