Configure pagination in gql query

Part of [laconicd testnet validator enrollment](https://www.notion.so/laconicd-testnet-validator-enrollment-6fc1d3cafcc64fef8c5ed3affa27c675)

Add `slashing` module for penalizing / jailing offline validators
Reference: https://docs.cosmos.network/main/build/modules/slashing#liveness-tracking

Note: Breaking change, an existing chain cannot be run with the updated binary
