This PR includes the changes to feature flags that were outlined in KIP-778. Specifically, it changes UpdateFeatures and FeatureLevelRecord to remove the maximum version level. It also adds dry-run to the RPC so the controller can actually attempt the upgrade (rather than the client). It introduces an upgrade type enum, which supersedes the allowDowngrade boolean. Because FeatureLevelRecord was unused previously, we do not need to introduce a new version. The kafka-features.sh tool was overhauled in KIP-778 and now includes the describe, upgrade, downgrade, and disable sub-commands. Refer to [KIP-778](https://cwiki.apache.org/confluence/display/KAFKA/KIP-778%3A+KRaft+Upgrades) for more details on the new command structure. Reviewers: Colin P.
