Add support to oslo.db to be used as a DB driver. The DB driver will be
used with API v2. When it's completely implemented, API V1 will be
deprecated and removed by the end of the cycle. Freezer-api will keep
supporting V2 with Elasticsearch, Sqlalchemy drivers.
This patch implements the follow:
* Abstract Base DB driver to be implemented by each driver
* Base driver; will return only access to the db engine, session
* SqlAlchemy driver;
* ElasticSearch driver;
* Implement both drivers in freezer-manage

This sets up the HTTPProxyToWSGI middleware in front of Freezer.
The purpose of this middleware is to set up the request URL
correctly in case there is a proxy (For instance, a loadbalancer
such as HAProxy) in front of Freezer.
The HTTPProxyToWSGI is off by default and needs to be enabled
via a configuration value.
