Merge lp:~gesha/linaro-license-protection/add-multiple-sites-support into lp:~linaro-automation/linaro-license-protection/trunk

[Georgy Redkozubov]

This branch adds support of multi-sites per single Django application. It is now configured to serve releases.linaro.org and snapshots.linaro.org. Both sites use the same database for licenses. License acceptance is site-dependent: for example if you have accepted the license on snapshots you will need to accept the same license on releases if asked.

Moved templates addition to own branch

[James Tunnicliffe (dooferlad)]

Looks fine.

Since we have multiple settings and wsgi files it would be possible to use a separate database for each site and remove the site_id requirement. The databases build themselves up as they go, so unless the OpenID code stores data in them, we can just delete the existing database at a later date and start fresh.

Currently the set up uses sqlite3, which is fine for development but not for deployment, but I assume you and the sys-admins know that and will use a more traditional database when live!

review: Approve

Removed not used SITE_ID. Can be added later if there will be a real need.
