Summary

Expose slashing params via Gaia-lite and CLI

Problem Definition

On voyager we were trying to track validator uptime (in this case defined as the amount of blocks they signed), which is possible with using the signing_info, but the problem is that we rely on the defaultSignedBlocksWindow to calculate the uptime on the rolling window. That means if the parameter is changed through governance clients won't be able to get the new parameter (besides of hardcoding the value).

Proposal

@alexanderbez : I think we should just expose everything that has a getter in slashing/params.go

Create a GET /slashing/parameters endpoint and CLI cmd to expose the params
