When rebooting the cluster, existing Labs are out of sync

[blues-man]

It looks we have some problems with Homeroom when cluster is stopped from RHPDS and restarted, existing labs are not getting right image hash and deployments fail.

From homeroom's log:

2021-01-26 09:58:16+00:00 [Warning] Failed to pull image "quay.io/openshiftlabs/lab-getting-started@sha256:f621a8faad2ba97611759c68d1384a87ef1ecb6690eb7776b87497424016f27e": rpc error: code = Unknown desc = Error reading manifest sha256:f621a8faad2ba97611759c68d1384a87ef1ecb6690eb7776b87497424016f27e in quay.io/openshiftlabs/lab-getting-started: manifest unknown: manifest unknown

The same type of error appears for the .NET, Java and Python workshops too.

Possible solutions/mitigations:

• use imagePullPolicy: IfNotPresent in spawner Pods
• use image tag versioning per release on Quay

Apparently fixed by removing ocp-ops-view from AgnosticV
