Helm operator 0.9.0

Bug fixes

• Make sure client-go logs to stderr weaveworks/flux#1945
• Prevent garbage collected HelmReleases from getting upgraded weaveworks/flux#1906

Improvements

• Enqueue release update on git chart source changes and improve mirror change calculations weaveworks/flux#1906, weaveworks/flux#2005
• The operator now checks if the HelmRelease spec has changed after it performed a dry-run, this prevents scenarios where it could enroll an older revision of a HelmRelease while a newer version was already known weaveworks/flux#1906
• Stop logging broadcasted Kubernetes events weaveworks/flux#1906
• Log and return early if release is not upgradable weaveworks/flux#2008

Maintenance and documentation

• Update client-go to v1.11 weaveworks/flux#1929
• Move images to DockerHub and have a separate pre-releases image repo weaveworks/flux#1949, weaveworks/flux#1956
• Support arm and arm64 builds weaveworks/flux#1950
• Retry keyscan when building images, to mitigate for occasional timeouts weaveworks/flux#1971
