Logarithmic scale: send function to giraffe to generate ticks

[TCL735]

Depends on influxdata/giraffe#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.

I just ran into a graph where I wanted to plot it logarithmically. +1 on FR

Another +1 for this, I used to make good use of logarithmic scale in 1.x, and I miss it in 2.0.

I also vote for this bringing back logscale in 2.x - in a small deployment it's too much overkill to use grafana on top of influxdb2.
