Renumbering of test files

[olivergs]

We should renumber test files according to some convention.

I.E.: All tests start with a 3 digit number. The first one is for component (0 for python modules, 1 for logger), the second and third one for module or feature (00 for database, 10 for sshcontroller and so on), so we can leave "blank" spaces in between (like 02, 13, or whatever) for adding tests in an specific order without having to rename all the test files.
