Support publish retry (Docker image pushing)

[jsirianni]

Sometimes pushes to dockerhub can fail intermittently, likely a brief issue with Dockerhub. Retrying the release usually works.

docker manifests: failed to publish artifacts: failed to push redacted/redacted:latest:
exit status 1: failed to mount blob redacted/redacted-amd64@sha256:631a09d22084b181ee5e32f354a3e6521b37ad879cb3210f8c44183adc4259f0
to docker.io/redacted/redacted:latest:
error parsing HTTP 403 response body: unexpected end of JSON input: ""

Ideally Goreleaser would support the ability to retry pushing docker images, with some sort of backoff configuration. Something we can opt into. e.g.

dockers:
  - id: alpine-amd64
    goos: linux
    retry:
      max: 5
      initial_interval: 10s
      max_interval: 5m

This would save time when releasing complicated software. We have a build that takes ~45 minutes to assemble. If the push to dockerhub fails, we need to retry the entire build.

Specifically I would like this for dockers and docker_manifests. Would be welcome to support retry elsewhere.

Alternatives

Alternatively, we would disable Goreleaser's push to dockerhub, and perform it with a script when dockerhub is finished. This is not ideal but could work.

hi!

it does retry image pushes, but I don't think it does it for manifests - it should!
