There's a cql_type_parser::parse() method that needs to get user
types for a keyspace by its name. For this it uses the global
storage proxy instance as a place to get database from. This set
introduces an abstract user_types_storage helper object that's
responsible in providing the user types for the caller.
This helper, in turn, is provided to the parse() method by the
database itself or by the schema_ctxt object that needs parse()
to unfreeze schemas and doesn't have database at those times.
This removes one more get_storage_proxy() call.
