Check for shard key or sort key before creating the temporary command

[jvelezmagic]

Summary:
This PR addresses a compatibility issue in Singlestore for incremental models using shard_key or sort_key. Previously, attempting to use these keys would fail due to an incorrect assumption that temporary tables are rowstore, which is not supported by Singlestore for CLUSTERED COLUMNAR indexes.

Details:

• Problem: Models with shard_key or sort_key couldn't be deployed as incremental tables because the system tried to create them as rowstore temporary tables, conflicting with Singlestore's requirements.
• Solution: We've updated the logic to dynamically set the storage type for temporary tables. If a model has shard_key or sort_key, it's created as a "temporary" table (compatible with these keys), otherwise, it defaults to "rowstore temporary".
• Benefits: This update ensures that all incremental models, regardless of their key configurations, can be deployed successfully in Singlestore.

Hi @jvelezmagic! Thank you for bringing this to our attention. In SingleStore, the SORT KEY()is not allowed when using CREATE ROWSTORE TABLE. However, there is no such restriction for shard keys. Therefore, I suggest retaining only the sort key check in the if-statement. If you encounter any issues with shard keys, could you please share the version of the adapter you're using and a model that triggers the problem?
