Issue submitter TODO list

• I've looked up my issue in FAQ
• I've searched for an already existing issues here (legacy) and here
• I've tried installing latest charts and the issue still persists there
• I'm running a supported version of the application & chart which is listed here

Describe the bug (actual behavior)

I think it will be useful to permit custom labels for deployment as already in place for pods (.Values.podLabels)

Expected behavior

possibility to set a new value (.Values.deploymentLabels ? ) with a list of custom labels for deployment
