feat: Logging level flag added

[ivan-velasco]

• feature: to partially solve this issue, introduced loggingLevel
• supported values are based on logrus package

"panic"
"fatal"
"error"
"warn"
"info"
"debug"
"trace"

#666

Additional discussion should occur as this logging package is in maintenance mode and performance is not the best. Migrate to a different library in the future. For instance https://github.com/rs/zerolog

Looks good

Hi @ivan-velasco , thank you for this proposal, this brings back this logs topic back.

We don't want to add a argument to manage log level, the verbose flag is here for that. Btw, here a PR to manage the log verbosity with the verbose flag (-v is INFO, -vv is DEBUG, default is WARN): #675
