Should `DEAD` state be included?

Review Comment:
Could you please avoid creating the `topicPartitionErrorsMap` for each loop
(`topic`)?

Review Comment:
should we check the null for `topicPartitionErrorsMap.get(topic.topicId())`?

not sure why the topic id is not set for the response

Review Comment:
we could reuse the `partition` instead of creating new
`AlterShareGroupOffsetsResponsePartition`, right?

Review Comment:
This behavior is not consistent with normal consumer tool. It should include
following tasks.
1. parse the string for "topic" and "topic partition". It means both
`--topicc a` and `--topic a:0` are valid
2. parse the `allTopicsOpt`
3. if `allTopicsOpt` is defined, all topics in the group should be reset.
4. if `topicOpt` is defined, all specified tps should be reset
