feat(pcli): support new ibc query logic

[conorsch]

Previously pcli was only capable of looking up info on IBC clients, connections, and channels if the user provided a unique identifier for the resource in question. To facilitate IBC in practice, we want to enable querying for lists of these values, so the end user (or developer) can inspect the current options in a legible format.

Closes #2937.

Wasn't able to drag the channel (singular) logic over to the new format, so I left that as the old k/v lookup.
