Add a test for deleting multiple objects by POST method
From swift Icehouse version, bulk deletion supports POST method as well as
DELETE.
Extra fixes:
- Bulk is an optional function with WSGI middleware, therefore each test
is annotated with @test.requires_ext
- Refactor test_account_bulk.py by separating common codes to one method
- Simplify delete_account method of the Swift's account service client
Partially implements blueprint add-icehouse-swift-tests
