Remove dependency on Tendermint logger

[ggarri]

Lightchain logger is inheriting from Tendermint logger functionalities (tmtLog "github.com/tendermint/tendermint/libs/log). This inheritance was not implemented correctly as the usage of Tendermint logger is spread around the entire Lighchain project (25 Occurrences)

The goal of this task is to fix the remove the dependency of Tendermint logger outside of the declaration of Lightchain logger module.
