Remove module/workspace name labels from output ConfigMaps

[jtdoepke]

Description

Labels on Kubernetes resources can only be 63 characters long. If the workspace/module name is longer than that, the controllers will go into an error loop. This PR truncates the ConfigMap labels at 63 characters.

I'll be the first to admit this is not a very good solution, and I am open to an alternative. I just didn't want to propose a breaking change without getting some input.

Alternatives:

• Make the labels into annotations instead.
• Do away with the labels entirely.
• Make any or all of the above configurable using CLI flags.

Usage Example

N/A

Hi @jtdoepke,

Thank you for raising this PR!

• Could you please sign CLA?
• Let's remove the ModuleName and workspaceName labels and leave workspaceID as it is (please do not truncate it). The workspace ID remains the same length and fits within the label length limit. I understand, that if that changes we will get into the same issue, however, on a long run distance we will need a more reliable solution. I like the alternative proposals that you made and we will definitely take them into account.

Thanks!
