Record state transition: snapshot submission to relayer

[anomit]

Fixes #40

Checklist

• My branch is up-to-date with upstream/main branch.
• Everything works and tested for major version of Python/NodeJS/Go and above.
• I ran pre-commit checks against my changes.
• I've written tests against my changes and all the current present tests are passing.

Current behaviour

As further detailed in the pooler issue PowerLoom/pooler#40, at present there is no information captured on the state transitions that a snapshot goes through from the point an epoch is released to it being finalized on the protocol state contract.

One of the important state transitions happens to be

• RELAYER_SEND - Payload commit service has sent the snapshot to a transaction relayer to submit to the protocol state contract

This information is required to be captured by the payload commit service to offer a complete view of the state transition status of a snapshot.

New expected behaviour

The payload commit service records the responses returned from the relayer or the barebones EVM node to which it sends raw transactions.

audit-protocol/go/payload-commit/service/service.go

Lines 255 to 265 in 406fdba

	go s.redisCache.UpdateEpochProcessingStatus(context.Background(), msg.ProjectID, msg.EpochID, "failed", err.Error())
	go s.redisCache.AddSnapshotterStatusReport(context.Background(), msg.EpochID, msg.ProjectID, &datamodel.SnapshotterStatusReport{
	SubmittedSnapshotCid: msg.SnapshotCID,
	State: datamodel.MissedSnapshotSubmission,
	Reason: "failed to submit snapshot to contract",
	}, false)
	return err
	}
	go s.redisCache.UpdateEpochProcessingStatus(context.Background(), msg.ProjectID, msg.EpochID, "success", "")

This information is stored against the Redis key REDIS_KEY_EPOCH_STATE_ID with the following data structure:

audit-protocol/go/goutils/datamodel/data_model.go

Lines 12 to 17 in 406fdba

	type SnapshotterStateUpdate struct {
	Status string `json:"status"`
	Error string `json:"error"`
	Extra map[string]interface{} `json:"extra"`
	Timestamp int64 `json:"timestamp"`
	}
