Reduced level of redundant logs

[merlimat]

Motivation

There are several logs messages, printed during the loading of a topic that are quite redundant in the information they provide.

eg:

One example is that on ledger creation, we're printing the ledger metadata, which contains the topic name (that we already know) and it gets all converted into byte[] so it's completely useless in the logs.
