database migration failed with missing QUOTAS option

[Jiajun Liu]

QUOTAS section was rename to quotas in commit: 362bd7fd09a5c6ff67e751ae5927f5b45deeac11

However the quantum/db/migration/alembic_migrations/env.py still using old QUOTAS to reference quota related options.

So when I perform any database migration action there will be some error like this:
