ROX-32852: Add filtering by cluster name

[mtodor]

Description

This PR is adding filtering by cluster name.

It first fetches the cluster to verify that the name exists and then uses the actual cluster ID in the query for a backend call. In that way, we can properly return an error if the cluster name does not exist.

Validation

• e2e test
• unit tests (new added)
• manual testing

Prompt: Is CVE-2020-26159 detected in staging-central-cluster?
