Added blazar as an alias package

Added blazar as an alias package of climate package. With this alias is
possible to rename imports in small patches that address only one or few
submodules. This will help the review process.
Modifications in setup.cfg:
    * Renamed some entries from climate to blazar
    * Added alias for console scripts
