Remove Trusty support from os_swift role

As a part of removing Trusty from OpenStack-Ansible we shall aim to
remove this from all the roles.

Testing has already been removed for Trusty in the integrated build and
all individual repositories on master (Ocata), as such we can now go
ahead and remove the support within the roles.

Change-Id: I89ba35fd15703aba2a05d11d4550690704bdf272
Implements: blueprint trusty-removal
