Replace active series with head stale metric

Is your feature request related to a problem? Please describe.
Cortex has a cortex_ingester_active_series metric to export data of recently ingester series by user. This data is controlled by Cortex with a copy of series with lastUpdate timestamp

Describe the solution you'd like
Prometheus just merge a change to add metric for stale series on head. prometheus/prometheus#16925
We want to replace current logic to use the new metrics from prometheus. We can still have the old metric based on new prometheus data.
