Summary

Add support for query parameters on staking queriers for Gaia-lite GET requests

Problem Definition

No current way to query staking parameters from validators or delegation txs.

Rephrasing @sunnya97 #2139 (comment):

It'd be nice for staking queriers to support query parameters so you can query specifically bonded, jailed, etc

Same applies for the state of delegations, unbonds and redelegations on a specific block height, which is currently supported on CLI

Proposal

Delegation txs:

For the following endpoints:

• delegator summary (delegators/{delegatorAddr})
• .../<delegations>/...
• .../unbonding-delegations/...
• .../redelegations/...

Queries supported:

• ?height=<block_height>: status at a specific block height.

Examples:

GET /stake/delegators/{delegatorAddr}?height=<block_height>
GET /stake/delegators/{delegatorAddr}/delegations/{validatorAddr}?height=<block_height>
GET /stake/delegators/{delegatorAddr}/unbonding-delegations/{validatorAddr}?height=<block_height>

Validators query

For the following endpoints:

• .../validators:

Queries supported:

• ?jailed=<true/false>
• ?status=<bonded/unbonding/unbonded>
• ?height=<block_height>: status at a specific block height. Useful to track voting power progress
• ?moniker=<name>
• ?website=<website>

Examples:

GET /stake/delegators/{delegatorAddr}/validators?jailed=true&status=unbonded
GET /stake/validators?height=32213
