Copy File Definition: Process multiple objects with single api request (#3163)

Refs https://github.com/openhab/openhab-core/pull/4734.

This solves the problem with YAML format returning the `version` and
`things` (or `items`) keys for each item in multi-select requests. By
combining them into a single request, only one key will be returned at
the top.
