Remove noop code

All these lines of code did was get a logger. Getting a logger is
a noop.

The comment says that this code was supposed to change the logging
configuration but it doesn't do that. Also, this isn't the correct
way to change the logging configuration, see
https://review.openstack.org/#/c/62068/

Cleanup from business logic refactor

This patchset resolves a few minor nits including proper translation
of a couple strings in exceptions, order of addCleanup in
test_keystoneclient, a simple white-space change to make a line
more readable, and adding a bug reference to a comment.  All of these
changes are in response to comments on the deletion business logic
refactor that moved business logic from the controllers to the *_api
managers.

Clean up fakeldap logging

The log strings in fakeldap were marked for translation and had
FakeLdap in each string. Let's save the translators' time and not
mark test strings for translation, and "fakeldap" is already in the
log message because of the formatter.
