Description

As part of further DistributedUpgrade code deletion, this jira proposes to remove ClientProtocol#distributedUpgradeProgress() and ClientProtocol#processUpgradeCommand

• related protobuf methods, requests and responses
• related java methods, request and responses

These are non-compatible changes. It should be okay to delete them, because this functionality has not been used for a long time(last used in 0.14)
