cardano-node should improve logging clarity

Area Other Any other topic (Delegation, Ranking, ...).

Summary Cardano-node logs include too much unnecessary haskell data-structure specific information. This is bad because it is increases log size without providing any additional value.

E.g.

Nov 10 12:13:07 relay1 cardano-node[66273]: [relay1:cardano.node.Mempool:Info:207475] [2022-11-10 20:13:07.06 UTC] fromList [("kind",String "TraceMempoolAddedTx"),("mempoolSize",Object (fromList [("bytes",Number 36322.0),("numTxs",Number 21.0)])),("tx",Object (fromList [("txid",String "879588a7")]))]
Nov 10 12:13:08 relay1 cardano-node[66273]: [relay1:cardano.node.LeadershipCheck:Info:154] [2022-11-10 20:13:08.00 UTC] {"chainDensity":4.8895936e-2,"credentials":"Cardano","delegMapSize":1226822,"kind":"TraceStartLeadershipCheck","slot":76544897,"utxoSize":8906282}
Nov 10 12:13:08 relay1 cardano-node[66273]: [relay1:cardano.node.Forge:Info:154] [2022-11-10 20:13:08.02 UTC] fromList [("credentials",String "Cardano"),("val",Object (fromList [("kind",String "TraceNodeNotLeader"),("slot",Number 7.6544897e7)]))]
Nov 10 12:13:09 relay1 cardano-node[66273]: [relay1:cardano.node.LeadershipCheck:Info:154] [2022-11-10 20:13:09.00 UTC] {"chainDensity":4.8895936e-2,"credentials":"Cardano","delegMapSize":1226822,"kind":"TraceStartLeadershipCheck","slot":76544898,"utxoSize":8906282}

Steps to reproduce Steps to reproduce the behavior:

1. Run cardano-node.
2. View the logs.

Expected behavior I hope the logs reduce the amount printed and improve readability overall.

@sunapi386 I aggree, especially we should not use show for data which contains Value (which is an intermediate representation of json in Haskell).
