Upgrades all transforms Added in 7.16.0

POST /_transform/_upgrade

This API identifies transforms that have a legacy configuration format and upgrades them to the latest version. It also cleans up the internal data structures that store the transform state and checkpoints. The upgrade does not affect the source and destination indices. The upgrade also does not affect the roles that transforms use when Elasticsearch security features are enabled; the role used to read source data and write to the destination index remains unchanged.
