Replace the current concept of extensions in Keystone

Registered by Henry Nash on 2014-11-10

The current extensions concept allows for experimental functionality to be introduced into Keystone. However, it leads to an increasingly complex set of wsgi components that may or may not be loaded, making it harder for other services/clients to be able to "interface with keystone". Experience from other projects (e.g. nova) suggests that as the number of extensions grows, the situation becomes unmanageable.

This blueprint proposes that the extension concept is replaces with the ability for functionality to be either be "stable", "experimental" or "out of tree".
