[kea-dev] kea apache cassandra/datastax cassandra

[Razvan Becheriu]

Hi,

I've updated the kea-admin script with the commands needed to initialize
the database and added necessary scripts to call the cqlsh (cassandra
database client).

I've attached to this file the necessary documentation needed to build the
datastax cpp driver and to build KEA with cassandra backend.
