[scalardl-auditor-monitoring] Collect metrics from same namespace only

[kota2and3kan]

Description

This PR updates the default configuration of kube-state-metrics.

Basically, we assume that the ScalarDL Auditor Monitoring chart collects metrics from the same namespace only as itself is deployed (i.e, it collects metrics of ScalarDL Auditor that is deployed in the same namespace as ScalarDL Auditor Monitoring).

However, in the current default value, kube-state-metrics collects metrics from all namespaces. Also, it requires a bit stronger permissions that are applied by using ClusterRole.

This PR sets (limits) the target namespace to the same namespace only as itself is deployed, and disables deploying unnecessary ClusterRole.

Please take a look!
