The default values should use the local swift installation, since these
are only used when the glance backend is set to "swift" it won't matter
if there is no local swift when the backend is set to "file".
Adjust AIO script to use the defaults.
Move the configuration values from user_secrets.yml into
user_variables.yml since these are not passwords that should be set.
Additionally comment them out by default.
