[Bug]: list-consumer-chains query does not support pagination

[dasanchez]

Is there an existing issue for this?

• I have searched the existing issues

What happened?

When I query the consumer chains in the ICS testnet using the Gaia CLI, I only get the first 100 with a next_page key:

gaiad q provider list-consumer-chains --node https://rpc.provider-sentry-01.ics-testnet.polypore.xyz:443 | tail -n 2 
  next_key: AAAAAAAAAAMxMDA=
  total: "108"

But there is no option to set the key or page.

Interchain Security Version

v6.3.0 (Gaia v21.0.0)

How to reproduce?

Query the consumer chains in the ICS testnet with Gaia v21.0.0:

gaiad q provider list-consumer-chains --node https://rpc.provider-sentry-01.ics-testnet.polypore.xyz:443
