Refactors the Keystone Authentication and Service Catalog classes to a
common model that can be used by V2 and V3 of Keystone. Each version
will have their own Authentication APIs and Service Catalog Suppliers,
and the higher level Keystone Authentication will transparently delegate
to the right API based on the keystone-version property.
OpenStack APIs will just have to define the default keystone-version
property they work with, and declare the generic Keystone Authentication
and Service Catalog modules.

When writing the ~/.ssh/authorized_keys file in a script that is being
run as sudo, the file is created with the root owner, instead of the
user defined by the node credentials. File ownership should be enforced
to make sure the right owner is alwaays set.
