[v3.0.0] Major Version - PVC updates and sidecars

[lenaxia]

Hi, this is a major update to enable fixing #32 while also making the helm chart more flexible for those who need to make changes.

This is intended to supersede #33.

Specifically:

• the images tag is now broken down into repository and tag fields to enable better automation for upgrading container
• persistence is now a top level field, moved out from under models to reflect the ability to define more volumes
• arbitrary volumes can now be defined under persistence, and will be default mounted to /, but can also be mounted using a globalMount option. This also prevents the recurrence of issues like Image generation issue #32 which cannot be fixed without a helm chart update
• initContainers and sidecarContainers allow creating or adding additional containers to do more work if desired
• download-models initContainer now also ensures that /tmp/generated/images and /tmp/generated/audio (for tts) are created

The values.yaml has been updated, and I highlight the updates below:

deployment:
  image:
    repository: quay.io/go-skynet/local-ai  # Example: "docker.io/myapp"
    tag: latest 
    
# Models to download at runtime
models:
  # Whether to force download models even if they already exist
  forceDownload: false

  # The list of URLs to download models from
  # Note: the name of the file will be the name of the loaded model
  list:
  #  - url: "https://gpt4all.io/models/ggml-gpt4all-j.bin"
      # basicAuth: base64EncodedCredentials

initContainers: []
# Example:
# - name: my-init-container
#   image: my-init-image
#   imagePullPolicy: IfNotPresent
#   command: ["/bin/sh", "-c", "echo init"]
#   volumeMounts:
#     - name: my-volume
#       mountPath: /path/to/mount

sidecarContainers: []
# Example:
# - name: my-sidecar-container
#   image: my-sidecar-image
#   imagePullPolicy: IfNotPresent
#   ports:
#     - containerPort: 1234

# Persistent storage for models and prompt templates.
# PVC and HostPath are mutually exclusive. If both are enabled,
# PVC configuration takes precedence. If neither are enabled, ephemeral
# storage is used.
persistence:
  models: 
    enabled: true
    annotations: {}
    storageClass: hoatPath
    accessModes: ReadWriteMany
    size: 10Gi
    globalMount: /models # if not defined, it will mount to /models
  output:
    enabled: true
    annotations: {}
    storageClass: hostPath
    accessModes: ReadWriteMany
    size: 5Gi
    globalMount: /tmp/generated

mh, this is breaking here with:
