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.
• Logs should be clear about whether they're logging Channel ID, Request transaction ID, on-chain transaction ID, or on-chain transaction receipt.
• If possible and easy, whenever we log the request transaction ID, we should also log the on-chain transaction ID.
