Provide missing hover hints for instance:<type> meters

Fixes bug 1243241

Previously, the Metric dropdown list on the Stats tab of the admin/
Resource Usage panel had hover hints with a short description of each
meter, except for the instance:<type> meters which were missing.

Now, we construct the hover hints list using the current set of flavor
names as reported by nova.

Fix horizon.tables.Column __init__ method.

__init__ method currently does not work (raises an exception)
when 'transform' arg is callable and 'verbose_name' arg is absent.
Fixed __init__ to use "" as default for 'verbose_name' when
'transform' is callable.
