Control log level via -v option
Some checks failed
continuous-integration/drone/push Build is failing
continuous-integration/drone Build is running

Allow the user to control the log level via the conventional `-v`
command line option. Multiplying this option-as per convention-increases
the verbosity.

This is an additional way to set the log level, in addition to the
existing:
- environment variable
- build type (debug vs release)

Given it is the most intentional and direct way to set the log level it
has precedence over all other options.
