             Summary: Multiple Consumer Group Management (Describe, Reset, Delete)
                 Key: KAFKA-7471
                 URL: https://issues.apache.org/jira/browse/KAFKA-7471
             Project: Kafka
          Issue Type: New Feature
          Components: tools
    Affects Versions: 2.0.0, 1.0.0
            Reporter: Alex Dunayevsky
            Assignee: Alex Dunayevsky
             Fix For: 2.0.1


Functionality needed:
 * Describe/Delete/Reset offsets on multiple consumer groups at a time (including each group by repeating `--group` parameter)
 * Describe/Delete/Reset offsets on ALL consumer groups at a time (add key `--groups-all`, similar to `--topics-all`)
 * Generate CSV for multiple consumer groups

What are the benifits? 
 * No need to start a new JVM to perform each query on every single consumer group
 * Abiltity to query groups by their status (for instance, `-v grepping` by `Stable` to spot problematic/dead/empty groups)
 * Ability to export offsets to reset for multiple consumer groups to a CSV file (needs CSV generation export/import format rework)
