Add more logs in the BN HTTP API during block production (#4025)

Browse Source 
## Issue Addressed

NA

## Proposed Changes

Adds two new `DEBG` logs to the HTTP API:

1. As soon as we are requested to produce a block.
2. As soon as a signed block is received.

In #3858 we added some very helpful logs to the VC so we could see when things are happening with block proposals in the VC. After doing some more debugging, I found that I can tell when the VC is sending a block but I *can't* tell the time that the BN receives it (I can only get the time after the BN has started doing some work with the block). Knowing when the VC published and as soon as the BN receives is useful for determining the delays introduced by network latency (and some other things like JSON decoding, etc).
