DB migration changes to support DB2 as sqlalchemy backend

Implements bp db2-database

SQLAlchemy works in general, only changes needed to allow DB2
backend are these migration updates. The main difference
with DB2 is around index creation and constraints updates.

Remove unused package in requirement.txt

This patch is similar to https://bugs.launchpad.net/glance/+bug/1252344.

Currently wsgiref/passlib package exist in requirement.txt,
but I confirmed that they are unused in glance source by "grep" command.

I removed them to clean up.
