Hacking check for opt name registration

Hacking check for opt name registration

Depending on how opts are registered (either with register_opt() or
register_opts()), the name needs to be singular or plural to match
the method.  This patch adds a hacking check to make sure the names
of the opts and opt lists (or tuples) are correct given how they are
being registered.  The check also verifies that a single option is
sent when register_opt() is used and a list is used when using
register_opts().

Includes fixes to files that don't meet the naming convention and a
addition to the generate_cinder_opts.py file in order to skip
checks.py in the generation of the opts.py file.
