Option ignoreNamespaceSelectors

[sentoz]

Request

Hello team, Grafana Alloy.

I would like to see an analogue of the ignoreNamespaceSelectors grafana-agent-operator function.
IgnoreNamespaceSelectors, if true, ignores NamespaceSelector settings from the PodMonitor and ServiceMonitor configs, so that they only discover endpoints within their current namespace.

Use case

In a large kubernetes, each namespace is a separate tenant and belongs to a separate team.
There is a need to prohibit collecting metrics from namespace B by creating a servicemonitor in namespace A.
Completely limiting the team to its tenant.

I needed this too, it seemed like a familiar functionality
