Title:
  migration default value not being applied to dbase

Status in OpenStack Neutron (virtual network service):
  Fix Released

Bug description:
  I have a private repo that is a few weeks behind the upstream, and was
  having problems stacking. Initially it was failing in one of the
  migrations, so I changed the SQLAlchemy version to 0.8.4 and alembic
  to 0.6.5 and retried (clean database).

  What I saw was that the migration worked, but later a router create
  failed.  It was complaining that the enable_snat field was not
  specified and did not have a default value. Checking in the
  migrations, I saw that 128e042a2b68_ext_gw_mode.py adds this field and
  sets the default value to True. However, it was not doing that.

  I changed the migration file to use server_default=sa.text("true") and
  now the migration works. BTW, it was the only migration file using
  'default=True'.

  Not sure if we should just apply this change to the existing migration
  file or if some other action is needed.
