a stack trace is reported when the keystone client attempts to list endpoints

[John Bresnahan]

When running the following command the service logs a stack trace and the client reports and error:

keystone endpoint-list
Failed to load keyring modules.
WARNING: Bypassing authentication using a token & endpoint (authentication credentials are being ignored).
Unable to communicate with identity service: {"error": {"message": "An unexpected error prevented the server from fulfilling your request. 'legacy_endpoint_id'", "code": 500, "title": "Internal Server Error"}}. (HTTP 500)

The error logged by the service is:

Not sure this is a bug; did you run db_sync? It looks like you're just missing one or more migrations.

[John Bresnahan (jbresnah)]

I did do: keystone-manage db_sync and it did not help. However, I then deleted the sqlite database and then did the same command and it did seem to solve the problem.

This ended up being a valid bug and was fixed in https://github.com/openstack/keystone/commit/31df378f as part of bug 1150930 where the same issue produced slightly different symptoms.
