Support stand-alone Cassandra integration about akka

[viktorklang]

I'm assuming from our previous discussion that we're talking about something like Cassidy?
Are there any hard requirements or do we make them up as we go? :)

New Thrift API:

public List<Column> get_slice_by_names(String keyspace, String key, ColumnParent column_parent, List<byte[]> column_names, int consistency_level) throws InvalidRequestException, NotFoundException, TException;

public List<Column> get_slice(String keyspace, String key, ColumnParent column_parent, byte[] start, byte[] finish, boolean is_ascending, int count, int consistency_level) throws InvalidRequestException, NotFoundException, TException;

public Column get_column(String keyspace, String key, ColumnPath column_path, int consistency_level) throws InvalidRequestException, NotFoundException, TException;

public int get_column_count(String keyspace, String key, ColumnParent column_parent, int consistency_level) throws InvalidRequestException, TException;

public void insert(String keyspace, String key, ColumnPath column_path, byte[] value, long timestamp, int consistency_level) throws InvalidRequestException, UnavailableException, TException;

I have started to hack this. Need to make it work with new thrift API, see prev comment. Do you want to own this task? If so I can just push my branch.
