metrics_server_spec.rb used a temporary directory to store Prometheus
metrics, but there is a class variable that stores the current
configuration. When the directory was wiped, the configuration was not
properly restored, so any subsequent specs that attempted to log metrics
would fail.

We fix this by restoring the old metrics dir in the config after the
spec runs.

The tabs select the scope of environments to show, and are synced to the
URL query parameters.

Testing the tab selection is a little tricky due to the reactive poll
interval, so if there is no interval, just skip polling.

This is also good in the event polling is disabled.
