In order to ANSIBLE_INJECT_FACT_VARS=False we have to use ansible_facts
instead of ansible_* vars. This change switches our distribution and
hostname related items to use ansible_facts instead.
All roles that have a hyphen in them need to be renamed to use an
underscore. This change creates a symlink to all roles using their
original name which will ensure we maintain compatibility with
the rest of the TripleO stack. This is being done because roles with
hyphens are no longer valid within collections.
A temp PBR update has been made to accomodate all of the symlinks to
the legacy role names.
