Add the ability to filter certain properties in the deal list

[jacobheun]

Purpose

Adds the ability to include filters when search for deals in addition to the existing query functionality. This should address all scenarios mentioned in #1014.

Example curls:

Get all offline deals pending transfer

curl -s -X POST -H "Content-Type: application/json" -d '{"query":"query { deals (filter: { Checkpoint: Accepted, IsOffline: true }) { deals { ID  Message} } }"}' http://localhost:8080/graphql/query

Get all deals currently in the sealing pipeline

curl -s -X POST -H "Content-Type: application/json" -d '{"query":"query { deals (filter: { Checkpoint: IndexedAndAnnounced }) { deals { ID  Message} } }"}' http://localhost:8080/graphql/query

Current Supported Properties

I've started with a subset of properties to filter by based on common scenarios. VerifiedDeal may be less useful atm, but there may be some useful applications there outside of the requested scenarios.

• Checkpoint
• IsOffline
• TransferType (Not currently supported in the UI as we havent had requests)
• IsVerified (Not currently supported in the UI as we havent had requests)

Work remaining

• Hook up the graphql resolver to pass filters from the client
• Fix the checkpoint filter so it's optional
• Add support to the UI to select the filters

Disclaimer: Still getting up to speed on go, so please suggest more idiomatic usage where applicable.

Resolves #1014
