Subject: [PATCH] add default optimization direction for 'fitness' and 'cost'

As we extend to more optimization objectives and explore constrained optimization it happens more often that we have a user-defined metric that defines the optimization objective. This pull makes it easy to specify the optimization direction, without the need to explicitly specify the direction using the  ``objective_higher_is_better=`` option of ``tune_kernel()``. Now, if your objective is named ``"fitness"`` Kernel Tuner assumes maximization and for objectives named ``"cost"`` or ``"loss"`` minimization is assumed.
