Replace nose with testr

- add .testr.conf (in base dir and nova_tests)
- remove all references to nose
- adjust paths: A couple of tests would assume the current directory
  was ./tests/ but it is now ./
- don't run the tests in parallel as the db tests have one connection
  per test class.

nova_tests hackery:
It seems testtools/testr imports everything and I just don't see a way of
running things in tests/ and nova_tests/ seperately but in one .test.conf.
So if you want to use testr directly you will need to:
 testr run
 cd nova_tests
 testr run
