Check that DWO is compatible with network-isolated clusters

Description

We need to make sure that DWO functions correctly in an airgapped cluster and document any issues or additional requirements that are needed.

Hi, a question to the assignee of this issue:

Will the outcome require any changes to the relevant content of the Installation Guide or Administration Guide or End-user Guide?

Yes/No?

@rhopp @dmytro-ndp folks, could you please point to the instructions that QA are using for the air-gap / network-isolated clusters setup? The plan is that @ScrewTSW is going to own the verification of the DevWorkspace running in this environment

[dmytro-ndp]

@ibuziuk: there is a set of scripts created by Radim and Flavius, which we are using downstream to setup OCP for CRW testing:

1. deploy disconnected OCP: https://gitlab.cee.redhat.com/codeready-workspaces/crw-jenkins/-/blob/master/jobs/CodereadyWorkspaces/Disconnected/orchestrator.Jenkinsfile
2. setup image mirroring and install CRW in there: https://gitlab.cee.redhat.com/codeready-workspaces/crw-jenkins/-/blob/master/jobs/CodereadyWorkspaces/Disconnected/installCRW.Jenkinsfile

Here the document prepared by Flavius: https://docs.google.com/document/d/1ZbzhoUYhV7gbZVJkX5o0kId8VOw1TNuWso89PNAP8uw/edit?usp=sharing

standalone DWO has been checked against airgap cluster.
Now we need to verify Eclipse Che 7.42.0 with the DevWorkspace enabled on the same environment

Closing as this should have been verified now

@ScrewTSW @musienko-maxim @dmytro-ndp folks, reopening this issue for clarification.
I'm not sure if this flow has been verified e2e with the recent fixes on the operator side.

Closing this issue after discussion and opening eclipse-che/che#21205 for e2e latest Eclipse Che verification in the air-gap mode.
