New Features
- Add Python 3.10 support.
- Add `--json` output option to `dwave sample`.
- Add `--sampling-params` option to `dwave sample`. `--num-reads` has been kept, and it now overwrites value given in sampling params.
- Add `--label` option to `dwave ping` and `dwave sample`, with a default value set. See [\481](https://github.com/dwavesystems/dwave-cloud-client/issues/481).
- Add `--full` option to `dwave setup`, propagated to `dwave config create`. Clarified `dwave setup` operation in CLI help.
- Filter out API token-like strings from logs. Most notably, we make sure to redact Solver API tokens, but will filter out any prefixed hex token. See [\391](https://github.com/dwavesystems/dwave-cloud-client/issues/391).
Bug Fixes
- Improved error and output handling in `dwave sample`. See [\300](https://github.com/dwavesystems/dwave-cloud-client/issues/300).
