**Is your feature request related to a problem or challenge? Please describe what you are trying to do.** <!-- A clear and concise description of what the problem is. Ex. I'm always frustrated when [...] (This section helps Arrow developers understand the context and *why* for this feature, in addition to the *what*) --> `Field::contains` currently checks for exact equality on `DataType`. For nested fields, this should be relaxed to instead call `Field::contains` or `Fields::contains` as appropriate. **Describe the solution you'd like** <!-- A clear and concise description of what you want to happen. --> I would like a `DataType::contains` method that behaves similarly to `Fields::contains`, `Schema::contains`, etc... and verifies that non-nested types are exactly equal, whilst using `Field::contains` and `Fields::contains` as appropriate for nested fields such as lists, structs and dictionaries. **Describe alternatives you've considered** <!-- A clear and concise description of any alternative solutions or features you've considered. --> **Additional context** <!-- Add any other context or screenshots about the feature request here. --> -- This is an automated message from the Apache Git Service.
