Visualizations: Histogram: add logarithmic scale for buckets + optional less than min, more than max buckets.

<!-- Please only use this template for submitting feature requests --> **Why is this needed**: I'm trying to create histogram for tests runtime distribution. The problem is that the histogram looks like `y=1/x` graph:  I had to create multiple histograms with different resolution and offset + limit maximum metric value in SQL to histogram's maximum to partially mitigate the problem.  **What would you like to be added**: * Add logarithmic buckets or a set of custom buckets. For example, for my case it would be good to have 0-1m, 1-2m, 2m-5m, 5-10m, 10-30m, 30m-1h, 1h-2h, 2h-5h, 5h-10h, 10h-1d, 1d-2d, 2d-1w. * Add _less than minimum_ and _more than maximum_ buckets (especially useful for linear bucket size). For example, _more than maximum_ bucket could be emulated via `least(metric, maximum)` SQL function + setting `maximum` property for Histogram, but it breaks calculation of additional values in histogram legend like `max` or `mean`, as Grafana no longer has access to real metric values. **Who is this feature for?** Users of histogram whose metrics have geometric-like distribution.
