Feature Request: Improve the Google Cloud Storage support with Jenkins Artifact system

[litan1106]

For example:
Improve the Google Cloud Storage support with Jenkins Artifact system like the S3 plugin and Azure Blob plugin.

Artifact Manager on S3 plugin is transparently used by the Jenkins Artifact system, so as other Artifacts Managers, you only have to use the Artifact Step to archive/unarchive, and the stash/unstash step, let's see how it works. We have also to mention here, the Copy Artifacts plugin that allow you to download artifacts from a finished build.

https://github.com/jenkinsci/azure-artifact-manager-plugin

S3 and Azure Blog plugin with Jenkins Artifact system integration offered simpler syntax and steps. (you can use same syntax for these two plugins but not Google Cloud Storage plugin.)

stage('Archive') {
    archiveArtifacts "my-artifacts-pattern/*"
}

stage('Unarchive') {
    unarchive mapping: ["my-artifacts-pattern/": '.']
}
