modules/db_cassandra Added new module DB interface for Cassandra backend
The module implements a database driver and can be used by other
modules to perform database operations instead of db_mysql, for
example. It has some limitations in the conditions on which the
queries are performed, so it does not suite every application. The
module has been tested with auth_db and usrloc modules and it is
very suited for implementing a distributed location service. Read
more about it in the README file.
