It would be nice if there was a bulk API for shelving projects in batch.

This would be used by seed jobs (via the job-dsl plugin) when unneeded jobs are automatically discarded and shelved. The bulk API would avoid avoid flooding the build queue with shelve tasks when there are many jobs to be discarded.

See https://github.com/jenkinsci/job-dsl-plugin/pull/1174#discussion_r292322461 for the request.
