test: moved to tools

Moved the current test folder to tools and started a new test
folder.  This will allow for rapid introduction of new unit-tests into
phosphor-hwmon.  The tools folder contains small tools to aid in
phosphor-hwmon configuration and misc.  This folder will go under review
at another time.
