Previously, if an AttributeError was raised in a plugin's make_client
method, the plugin simply wouldn't be an attribute of the ClientManager,
producing tracebacks like
Traceback (most recent call last):
File ".../openstackclient/shell.py", line 118, in run
ret_val = super(OpenStackShell, self).run(argv)
...
File ".../openstackclient/object/v1/container.py", line 150, in take_action
data = self.app.client_manager.object_store.container_list(
File ".../openstackclient/common/clientmanager.py", line 66, in __getattr__
raise AttributeError(name)
AttributeError: object_store
This made writing minimal third-party auth plugins difficult, as it
obliterated the original AttributeError.
Now, AttributeErrors that are raised during plugin initialization will
be re-raised as PluginAttributeErrors, and the original traceback will
be preserved. This gives much more useful information to plugin
developers, as in
