* create/show mapping
* create/show identity provider

Remove links from oauth consumers

This should be the last of the v3 identity objects that return
a links section upon create or show.

Add an API example base and functional test base

Add examples/common.py, which is a basic common setup that mimics OSC's
configuration options and logging without the rest of the CLI.

Also add the functional test tooling for examples to prevent bit rot.
