Using abbreviations for under-replicated-partitions and offline-partitions breaks the pattern used everywhere else. Even within these two new commands, it's not consistent: you have urpCmdConfg, underReplicatedPartitionsCmd, GetUnderReplicatedPartitions, urpCommand, FormatURPs, etc.

I realize they are long but I think it's better not to use abbreviations and be more consistent.

This log format and the debug flag should already be getting set by the root command that these subcommands are added to

I think we can remove some duplicate code by adding this to the get subcommands prerun

--debug is noted as being a "global flag". Isn't this already set somewhere higher up the stack?

The term "under-replicated partitions", when output, is inconsistently written. I would suggest "under-replicated partitions" (with the hyphen between under and replicated, and not capitalized) because that is most grammatically correct IMO.

The more I think about it, do we even need these new types? Couldn't we just reuse TopicInfo and leave the unused fields blank?

Partitions []PartitionInfo `json:"partitions"`

I think we should be converting []kafka.Partition into []PartitionInfo for consistency
