GP: "Run Test" behaviour update

[alexey-yarmosh]

I think "Run Test" behaviour may be a bit updated to provide more value with fewer user actions:

1. Current default limit is 10. But it may result in e.g. 5 EU probes and 5 NA probes. "World" filter should be updated to include every region (with exception for AF and OC probably, as there are not so many probes there).
2. Table view of the results may be a default if available and there are >1 results (as I want to compare results first, and dive deeper in CLI output further). Additionally row click may switch to CLI view, scrolled to the clicked measurement.
3. Looks like table view may also be implemented for http measurements. => GP: Expand table mode to support more tests #606
4. Graph column should have the same Y scale for all measurements. Shades work great on the map, but with bar charts it is hard to compare the values in current implementation:

I'm not sure if I agree with 1 and 2, and for 3 we have an issue open. 4 I definitely agree.
