Improve Request Node Logging

[MantisClone]

Problem

The Request Node logs are difficult to read and analyze.

• information is split across separate logs so it's hard to correlate the logs

Proposed Solution

• Every endpoint on the gateway should log the incoming request and the outgoing response.
• Label all data - Logs should be clear about whether they're logging Channel ID, Request transaction ID, on-chain transaction ID.
• If possible and easy, Whenever we log the request transaction ID, we should also log the on-chain transaction ID and the IPFS CID
• Whenever the Request Node times out we should log it.
