feat: [v2] add new chart

[crandles]

Revamped chart & chart release workflow.

You can try the chart I published in my own ghcr namespace:

helm install trickster oci://ghcr.io/crandles/charts/trickster-v2

Note: last published under trickster-v2 name.

or to setup and install via kind:

TRICKSTER_ORG=crandles make setup-kind install query

Notes:

• Retooled chart around a single associated persistentVolume
• Very limited config objects are modified by the chart (ports, default paths); but they can all be overriden
• Allow for override labels/annotations of every resource
• Tested locally: with prometheus backend, default cache, with a pvc, with ingress, with nodeport
• Updated Readme
• Added release workflow & tested via fork

---

To Do:

• Allow label/annotation overrides, per-object
• test locally (deferring testing via workflow to another PR)
  • pvc
  • ingress
  • nodeport
  • local prometheus target
• review trickster configs closer; looking for values that need special attention in helm template
  • configure caches to use PVC/emptyDir storage path
  • set server/metrics listen port via service.* values
• allow override of ENV vars & CLI Flags
