Use default settings instead of repeating the options
for each class.
Add docstrings for special methods that do not have them
so they appear in the output.

before loading any code to avoid importing anything we are not going
to use.

Sometimes we want to use AssertionError to cause test
failures, and it is unlikely to be used in real code,
so just let the error bubble up if it is encountered
while loading a plugin.

Scanning the entry point registry is relatively expensive
and causes performance issues with unit tests of code
depending on stevedore. This change addresses the
performance issues by caching the entry points as
they are loaded from pkg_resources in a class attribute
in the base class of the extension managesr so they can
be reused by other instances.

Go ahead and load the extension entry point so the
check function can interrogate it about whether it
should be enabled or not.

Create a special extension manager class that uses pre-configured
extension instances instead of loading them from a plugin set.
This makes setting up controlled environments for testing much
easier.
