CI pipeline for maintaining the release

[bgandon]

Gstack has developed a Concourse pipeline and demonstrated ability to update dependencies and ship a new release v0.4.3 using it:

• See: gstackio/bosh-virtualbox-cpi-release/releases
• Based on CF community standard pipelines, see: cloudfoundry-community/pipeline-templates
  • A model that is already successfully used for maintaining several bosh releases, concourse resources, and golang CLI tools
  • Custom “bump-golang-blob” job for bumping golang package, run a testflight, and commit
  • Custom “bump-deps” job for bumping golang deps, compile, test, commit

Submitted here for contribution to the CFF upstream.

Fixes #33.

I should rework the contribution branch so that it does not include the version bumps themselves. They make the code review difficult and I can always cherry-pick those later on.

Here we go, that's cleaner.

Worth to note, everything in the ci folder is generated from the pipeline template, except ci/settings.yml.

settings.yml is where all the Spruce customisations are. these are being merged on top of the generated pipeline.yml by the repipe script.

As mentioned during working group meeting the shared golang scripts should be good to consume now: https://github.com/cloudfoundry/bosh-package-golang-release/tree/main/ci/tasks/shared

Consider using go run github.com/onsi/ginkgo/v2/ginkgo here so that there isn't a need for a ginkgo binary to be installed in $PATH, and to ensure that the version used matches go.mod.

Example: https://github.com/cloudfoundry/bosh-agent/blob/main/bin/ginkgo#L5C1-L5C40

Maybe it makes sense to use set -e instead of the result+=$? pattern. It reduces conditionals, and ensures the script fails early.

Example: https://github.com/cloudfoundry/bosh-agent/blob/main/bin/ginkgo#L2

Thank you for all these updates! I really appreciate the thoroughness, and attention to detail in this change.
I'm not super familiar with this CPI so I will defer to others as to the functional changes.

Thanks for the review, I'm going back to this

@bgandon are still planning on coming back to this, or should we merge it as is?
