Move test_os_server and apply fixes.

- Add missing meta value for test_create_server
- Add .gitignore for pytest .cache directory

Exclude test_os_server from nose test runs since it was designed
for pytest. The test will work correctly when run using pytest.

This is a temporary issue, as we'll be moving to pytest soon.
