Add support for downloading published Artifactory build-info object from Artifactory and append using the Jenkins-jfrog-plugin

Is your feature request related to a problem? Please describe.

Consider the following use case where we are running a multi-branch pipeline that is having 3 new branches within it(i.e branch1, branch2, and master maintaining the same build name & number) and maintain a single buildinfo object in Artifactory by publishing it from each branch.

1. Publish buildinfo of the first pipeline branch to Artifactory
2. Then, download the existing buildinfo of the above build from Artifactory and append it to the current buildinfo of the next branch, and publish it again to Artifactory.
3. Similarly, download the latest buildinfo (for the above build number) from Artifactory and append it to the current buildinfo, and publish it to Artifactory.

Describe the solution you'd like to see

Currently, appending a published build-info into an unpublished build-info is not supported. Hence, Looking for an option to download buildinfo object which was published as part of the previous build stage, and append it to the current stage build object so that we can maintain an aggregated buildinfo of the multi-branch pipeline.

@tataraov,
The build-info is immutable by design. However, you can logically add a published build as a module to the current build. This feature is named build-append.
