Title:
  _is_opt_registered does identity check

Status in OpenStack Compute (Nova):
  Fix Released
Status in openstack-common:
  Fix Released

Bug description:
  When using _is_opt_registered  (of cfg) it seems like there is a
  identity check that happens here instead of an equality check.

  In glance, it was suggested to define the options inside a function,
  and then register the opt when that function is entered, this of
  course makes the opt registration blow up, since the option will not
  be "identically" the same (due to a previous function call occurring
  with a different opt, that is equivalent but not identical).

  This also will happen if opts are defined inside classes (ie anywhere
  not globally) and that class is constructed twice or a function that
  defines them is called twice (thus causing duplication option errors).

  Possible this line:

  if opts[opt.dest]['opt'] is not opt:

  Should use equality (or check on the names??)
