Convert all consensus node logging to use the base logger directly

Remove the need for the log4j to base logger bridge. Once this ticket is done, there should be no direct dependency on log4j from the consensus node code.

Start by locating the consensus node code and every use of the log4j-to-base logger bridge. Replace the bridge-based logging with the base logger directly, then verify that consensus node code has no direct log4j dependency.
