Draft: Change functional tests to the new structure.

I change functional tests to the new structure using nosetests.

Existing functional tests has the following problems.
- File name becomes the nonsense sequence number.
- Large quantity of files will be located in one directory when we add tests because it becomes 1 file every 1 test.
- Because the system is such that it is more special than other products of OpenStack, it is hard to develop it.

I think that the problem mentioned above are solved by this patch.
