[Data Usage] New plugin

[neptunian]

The initial plugin for viewing data usage and retention in Management. The purpose of this PR is to provide a place for other engineers to work on it, hidden from public use.

• Plugin is hidden by default and can be enabled through kibana.yml
  xpack.dataUsage.enabled: true
• Currently it will show up in both stateful and serverless (if enabled using config above). When we are ready to make the plugin available we will enable it in config/serverless.yml
• Renders as a card in serverless management:
