ff55b76562 cql3::query_processor: use weak_ptr for passing the prepared statements around 
Use seastar::checked_ptr<weak_ptr<pepared_statement>> instead of shared_ptr for passing prepared statements around.
This allows an easy tracking and handling of statements invalidation.

This implementation will throw an exception every time an invalidated
statement reference is dereferenced.

7bd4b7ca63 cql3: split use_statement into raw and prepared variants 
Rather than having one class fulfil both roles, have one class per role,
disentangling dependencies.
