Logarithmic scale: send function to giraffe to generate ticks

Depends on https://github.com/influxdata/giraffe/issues/483

After Giraffe has implemented an option to pass a function to generate ticks, the UI will consume that feature to allow the user more control over tick mark generation with logarithmic scales.

The UI will present the user a choice of where to place tick marks on a logarithmic scale. As an example, possibly something like, "Mark ticks at 10^1, 10^2, 10^3,... etc. for base 10 log.
