[Chore] Single line for message logging

[ntallar]

Description

As we are currently logging all messages, it can be a bit of a pain to read logs with all the structures being printed as multiline, this changes for them being single line.

(my first thought was removing that logging entirely, but it ended up being useful for tracking blocks on the testnet)

Testing

Checking that I didn't miss any structure or message

I think there are still some multiline messages (i search by stripMargin).. what about these ones?

src/main/scala/io/iohk/ethereum/blockchain/sync/FastSync.scala
src/main/scala/io/iohk/ethereum/ledger/BlockPreparator.scala

I addressed all but these, as they are not structure/message logs nor they have been a nuisance to me when running Mantis locally, but I can change them if you prefer

hmm...maybe just the one related to FastSync? or change the rest just to be consistent on the approach WDYT?

Just curious: what is wrong with multiline logs? We have already implemented logging.json-output to use with graylog

[ntallar]

That locally I like running Mantis with logging.json-output set to false 😛 this change is not for the testnet but for me or anyone that runs Mantis locally with that disabled (and it doesn't affect those who don't disable it)
