Related to #16864
Internally the put pipeline API uses this information in node info API to validate if all specified processors in a pipeline exist on all nodes in the cluster.
This is a simple port of the mapper attachment plugin to the ingest
functionality, no new features. The only option is to limit
the number of chars to prevent indexing of huge documents.
Fields can be selected in the processor as well.
