The code has been moved into openstacksdk. Make os-client-config a
thin wrapper around that code.
The legacy client code needs to stay, as it was removed in openstacksdk.
We also have to plumb os_client_config.defaults and
os_client_config.cloud_region.CloudRegion in so that users get the
os-client-config versions from the openstacksdk methods that return the
relevant objects.
Support for per-service region_name has been dropped. This was never
used anywhere and was added for compatibility with openstacksdk Profile
objects. Since Profile objects are no more, we can remove it. It never
made any sense.

In preparation for sharing the default and vendor data with other
projects, potentially even non-python ones, move the data into json
format, which is slighly less exciting to read, but has more widespread
standard library support. The user-facing config file will still be in
yaml format, because that's easier on the eyes and it's expected to be
read and edited by humans.
Continue to accept yaml everywhere, because an end user may have dropped
a yaml config file into a dir somewhere, and that's fine.
