Now that we've done T365626: move k8s opentelemetry-collector from services to admin_ng, it's easy to make more deployments of the otel collector to test out new configurations.
Let's add deployments in staging clusters of both eqiad and codfw.
This will make it easier to test the WIP of T363407. And we'll want this in the future anyway, as it's looking like the OTTL rules we'll be distributing will be non-trivial.
