List of offline validators during an upgrade

[jackzampolin]

We should build a tool that allows querying for a list of offline validators ranked by voting power (highest to lowest) by name for upgrades. This should help with upgrade coordination

Note this one pulls the validator info from a genesis file, if the RPC is online we can use q staking validators instead.

We would get this by just inspecting the latest block. It'd be great to also allow passing in a historical block (or block range). This could enable report generation for downtime events and other use-cases. I'm planning to pick up this ticket in the next couple days.
