This change removes all SSH-related components, their configuration
options, and tests.
SSH is such a low-level service (from the perspective of any operator
deploying a cloud), that it is reasonable to assume that (or provide
direction that) SSH must be installed and configured prior to usage of
the puppet-swift module.
Without this change, there is a significant liklihood of confusion
occurring in the likely case of SSH being managed elsewhere.
