Custom kaniko image is ignored

[everflux]

Expected behavior

When specifying build.kaniko.image it is possible to choose a custom image instead of the default gcr.io/kaniko-project/executor:v0.7.0@sha256:0b4e08... image.

Actual behavior

The default image is always used.

Information

• Skaffold version: v.0.22.0
• Operating system: linux
• Contents of skaffold.yaml:

apiVersion: skaffold/v1beta4
kind: Config
build:
  artifacts:
  - image: localhost:31000/kaniko-demo
  kaniko:
    buildContext:
      localDir: {}
    Image: localhost:31000/kaniko/executor
    namespace: default
    cache: {}
deploy:
  kubectl:
    manifests:
    - k8s-*

Steps to reproduce the behavior

1. skaffold run produces a pod with the (pinned) default skaffold executor image

Hey @everflux , I think I introduced this bug when refactoring kaniko, sorry about that! I've opened a PR to fix it.

I tested with a local skaffold build and it fixes the issue, thanks for the really awesome quick turn around!
