We use `data_resource` class in the CQL parser, which let's users refer
to a table resource without specifying a keyspace. This asserts out in
get_level() for no good reason as we already know the intented level
based on the constructor. Therefore, change `data_resource` to track the
level like upstream Cassandra does and use that.
Fixes #1790
