    add logging for starting request  and receiving block (#3858)

    ## Issue Addressed

    #3853

    ## Proposed Changes

    Added `INFO` level logs for requesting and receiving the unsigned block.

    ## Additional Info

    Logging for successfully publishing the signed block is already there. And seemingly there is a log for when "We realize we are going to produce a block" in the `start_update_service`: `info!(log, "Block production service started");
    `.  Is there anywhere else you'd like to see logging around this event?
