Major Ingress update

Release v0.19.0 marks addressing a major breaking change.

With #305 merged we officially stop supporting older version of kubernetes leaving only support for 1.18+ features.

We have created a guide for all those, still on the older versions, that should help in the transitioning process:

From 0.19.0

Since this version we support only kubernetes >= v1.18 for the ingress definition.

If you enabled ingresses you need to migrate values from:

ingress:
  read:
    hosts:
      - host: chart-example.local
        paths: ["/read"]
  write:
    hosts:
      - host: chart-example.local
        paths: ["/write"]

to

ingress:
  read:
    className: ""
    hosts:
      - host: chart-example.local
        paths:
          - path: /read
            pathType: Prefix
  write:
    className: ""
    hosts:
      - host: chart-example.local
        paths:
          - path: /write
            pathType: Prefix

where changes are on:

• introduce the className to specify the ingress class documentation that need to be used
• change paths definition from an array of strings to an array of objects, where each object include the path and the pathType (see path matching documentation)
