Add wg-easy applicaiton example with helmfile and taskfile flow

[chris-sanders]

This is not currently ready for merge, but it does demonstrate the folder layout and uses taskfile and helmfile as a pattern separate from umbrella charts.

Issues to address before merge:

• There are some hard coded values in the taskfile that makes assumptions about application name
• Reimplement the expose functionality for CMX to at least test/demonstrate TLS working
• Re-add the SDK as a stand alone chart
  • Test a replicated release on CMX (so the SDK can be used)
• Look to address duplicate additionalNamesapce in Application with the per-chart settings
• Look to address duplicate version numbers where HelmChart must match Chart.yaml
• Add a readme and explain
  • Folder structure
  • Development/test flow
  • Helmfile pattern
  • Taskfile pattern
  • local charts/template pattern
  • Diagrams?

There's more integration to be done with Replicated platform but the above were at least my intentions with this chart before merge. I want to explore this pattern and how the development/release flow works including using CMX to incrementally test with the smallest possible feedback loops.

• The release name 'wgeasy' is inconsistent with the application title 'wg-easy', which may lead to confusion. Align the naming between these fields.

  name: wgeasy

applications/wg-easy/helmfile.yaml:27

• The dependency reference 'cert-manager/cert-manager' in the 'needs' field for the cert-manager-issuers release does not clearly correspond to an existing release name, leading to potential misconfiguration. Verify that dependency names match the intended release identifiers.
