Compute cluster upgrade

On Sat, 2023-04-01, compute cluster will be upgraded.

Our infrastructure team will upgrade control-plane components and some foundries.io services.
During the maintenance, OTA and CI systems might have service interruption (expected downtime - less than 5 minutes). Docker registry hub.foundries.io might be unavailable up to 10 minutes.
Performance of some foundries.io services might be impacted during the maintenance.
