Title:
  Migrate script 203 doesn't work with SQLAlchemy 0.8.x

Status in OpenStack Compute (Nova):
  Fix Released

Bug description:
  Using SQLAlchemy 0.8.x I get the following traceback when migrate
  script 203 is applied:

  Traceback (most recent call last):

  TypeError: __init__() got an unexpected keyword argument 'assert_unicode'

  Keyword argument   'assert_unicode' had been deprecated for a long
  time and was removed in 0.8 release.

  According to the changelog message
  (http://docs.sqlalchemy.org/en/latest/changelog/changelog_08.html
  #change-ad44af79c886d1bb283042deb64f9cbe) and corresponding commit
  message
  (https://bitbucket.org/dimonji/sqlalchemy/commits/d576b5fd0cb9fc7928d77aa3411b5b1efab36c07)
  this keyword argument was non-functional, so it can be safely removed
  from the existing migrations script to make it work correctly for both
  SQLAlchemy 0.7.x and 0.8.x branches
