## What changes were proposed in this pull request? In the PR, I propose to add `maxFields` parameter to all functions involved in creation of textual representation of spark plans such as `simpleString` and `verboseString`. New parameter restricts number of fields converted to truncated strings. Any elements beyond the limit will be dropped and replaced by a `"... N more fields"` placeholder. The threshold is bumped up to `Int.MaxValue` for `toFile()`. ## How was this patch tested? Added a test to `QueryExecutionSuite` which checks `maxFields` impacts on number of truncated fields in `LocalRelation`. Closes #23159 from MaxGekk/to-file-max-fields.
