universal-query: Add query() to ShardOperation trait

[coszio]

Needs #4209

Still some partial implementation for shard handling of query requests:

• Adds a new query() required method on the ShardOperation trait, which receives the ShardQueryRequest type.
• Includes the conversions needed to go from ShardQueryRequest to the grpc QueryShardPoints types
• Moves itertools to the workspace dependencies
