Set default log level to 'Info'

Currently 'Info' level logs are only shown with the '-v' flag. This
makes commands without the '-v' flag of little use to users, especially
on success cases, due to no output.

This commit will set the default log level to 'Info', and passing a '-v'
flag will log at a 'Debug' level.
