Support Redshift serverless

[elic-eon]

🤔 Why?

Since Redshift serverless only supports SYS monitoring views we need to migrate our query log fetching SQL to SYS_* view.

Note that we need to grant new permission to get user name from user_id

🤓 What?

As described above, rewrite the query log fetching SQL, and use the util function to get sources and targets.

🧪 Tested?

Verified against Redshift provisioned and Redshift serverless.

☑️ Checks
