Impossible to execute storage tests selectively due to missing import

[Balazs Gibizer]

Storage tests fail if they are executed selectively due to missing gettextutils import in ceilometer.storage.base.

$ tox -e py27 -- storage.test_storage_scenarios

Adding the missing import solves the problem:
