Rename the subdirectory and replace all instances
of "import savanna" with "import sahara" and all
instances of "from savanna" with "from sahara".
* Replaced mock patches like mock.patch('savanna...
* Updated config generator script
* Renamed entry points in setup.cfg
* Hacking checks also fixed
* Manual renaming in alembic scripts to force work migrations
* Fix doc building
* Renamed itests directories
* Some changes in gitignore
* Removed locale dir after rebase
