[CLI] Improve debug and verbose printing

[getzze]

From #1131 (comment)
"do we have to print Not using any configuration file. every single time? wouldn't it be better as a debug print?"

And #1131 (comment)
"The problem is that when the config file is parsed, the logger is not set yet therefore the message is "printed".
Another problem I saw is that the two options --debug and --verbose are redundant."
