    Parallel test execution with py.test

    Patch adds ability to execute test run distributed over
    several processes, each one with isolated database.

    Assumptions:
    - nailgun user, requires createdb permission, if not please precreate
      databases in format described below
    - postgres database will be used for initial connection
    - for environment where createdb can not be granted, like ci
      operator need to create several databases, nailgun[0-7],
      count of databases should be equal to TEST_WORKERS variable
    - If no TEST_WORKERS provided - default database name will be used,
      it is almost every time nailgun, but you can overwrite it with
      TEST_NAILGUN_DB env variable

    To execute tests on your local environment:
      py.test -n 4 nailgun/tests/
