Combine helm chart

[bstrdsmkr]

Is your feature request related to a problem? Please describe

The helm chart should be tested with each new release of the Metagrid stack and vice versa.

Describe the solution you'd like

Should we move the helm chart repo into the Metagrid repo to facilitate this testing? This is a fairly common pattern for stacks with multiple supported deployment methods like this.

Describe alternatives you've considered

Keep the helm chart and stack separate. This maintains separation of concerns, but makes testing much more manual
