[IMPROVE] Hourly rocketchat_users metrics refresh rate

Description:

The Prometheus metrics for rocketchat_users_* (rocketchat_users_active, rocketchat_users_active, rocketchat_users_away, rocketchat_users_non_active, rocketchat_users_offline, rocketchat_users_online and rocketchat_users_total) seem to be refreshed only once per hour. This may also be the case for the data displayed in the rocketchat administration panel.

Steps to reproduce:

Setup a Prometheus monitoring instance with Rocketchat

Expected behavior:

Other metrics, such as rocketchat_ddp_connected_users have a much faster refresh rate, which can be very useful. I would expect rocketchat_users_* to be refreshed in a similar way.

Actual behavior:

rocketchat_users_* is refreshed once per hour.

Server Setup Information:

• Version of Rocket.Chat Server: 4.4.0
• Operating System: Docker setup using the official rocketchat image
• Deployment Method: Docker (Openshift)
• Number of Running Instances: Tested on three different instances

Search the codebase for the rocketchat_users_* Prometheus metrics and compare their refresh path with rocketchat_ddp_connected_users. Verify whether the administration panel uses the same data, then confirm that the user metrics refresh faster than once per hour and add or update coverage for the new behavior.
