Provide conversion webhook for CRDs

[sgraband]

Webhook is called, whenever a CR is requested in a specific version. This allows for a better updating path, as old CRs are still useable.

[conversion] Provide conversion java project:

• A webhook that offers endpoints for the three CRD types
• Is buildable as a runnable jar
• Contains Mappers from all supported versions to a hub

[common] Add Hub and previous version for all CRDs

• The hub is a superset of all values of a CRD across all versions

• Keep a copy of the old supported versions to transform back

• This is useful, as this way the the old operator still works

• Supported from these versions: - AppDefintion.v1beta8 - Session.v1beta6 - Workspace.v1beta3

• To showcase the functionality update CRDs to new version: - Move status like fields to status: - Session.v1beta7: Move url, lastActivity and error fields from the spec to the status. - Workspace.v1beta4: Move the error field from the spec to the status. Also add the error field to Workspace.v1beta3 as it was missing

  • Remove timeout.strategy from AppDefinition
    • AppDefinition.v1beta9: Removed timeout.strategy and timeout.limit
      is now just timeout. This was done, as there is only one Strategy left.

[operator] Adjust operator so it works with the above changes.

[service] Adjust service so it works with the above changes.

[documentation] Add build command for conversion-webhook

[.github] Add ci for conversion-webhook

• Also fix publishing of new next-version (reusable typo)
• (I pushed the missing images manually)

I've pushed some missing eclipse metadata files and opened all java projects with Eclipse (2023-03), VSCode, and the TheiaIDE and committed the resulting updates to the metadata files.

I noticed that there are some left over theia.cloud/v1beta8 AppDefinition references in:
demo/dockerfiles/demo-operator-custom-template/templateDeployment.yaml
demo/dockerfiles/demo-operator-custom-template/templateDeploymentWithoutOAuthProxy.yaml
helm/theia.cloud/test/cdt.yaml
terraform/test-configurations/2-01_try-now/theia_cloud.tf
terraform/test-configurations/2-03_try-now_paths/theia_cloud.tf

Could you please check if you get changes on the settings in different IDEs? If yes we should check if we can fix this (probably in a follow up ticket), because the settings should not get added to .gitignore, if possible.

Thanks, I had a first look at the code and it looks very good already.
I will start some testing now as well.

Looks good on my side. Tested also with VSCode, TheiaIDE and Eclipse

I did a first test and found one issue (see inline comment).
Overall everything looks pretty good. I had no issues with certificates and the conversion was triggered smoothly.

I will do more testing on Friday

[jfaltermeier]

I've found two more mixups in the Hub.
After those are fixed, I think we can approve and merge this.
This was the only issue I found during the second test.

Also I pushed one commit updating the AppDefinitions in the tf files I used for testing

Thanks, LGTM!
