Enable Resource Actions in clusterGroup chart

[day0hero]

** Enables the existing feature of resource actions in the clusterGroup chart.

Reasoning

What do we gain from this? Enabling this allows us to make a better UX for our users where an action is required to be taken. For example, one pattern may need to scale the replicas of a deployment, another may need to patch a resource for DR failover/resync. Instead of having users run commands from the cli, or hunt for it in the UI, we can build a "button" of sorts to allow them to do this trivial task.

Resource Actions

Custom resource actions can be configured on the ArgoCD instance via clusterGroup.argoCD.resourceActions.
This allows defining Lua-based actions that appear in the ArgoCD UI for specific resource kinds.

For example, to add a "scale up" action for Deployments:

clusterGroup:
  argoCD:
    resourceActions:
      - group: apps
        kind: Deployment
        action: |
          local os = require("os")
          local actions = {}
          actions["scale-up"] = {["disabled"] = false}
          local replicas = 1
          if obj.spec.replicas ~= nil then
            replicas = obj.spec.replicas + 1
          end
          local patch = {["spec"] = {["replicas"] = replicas}}
          return actions, patch
