NETOBSERV-787 UI: Table Histogram

[jpinsonneau]

This implements histogram UI component based on #270 query.

The range is forced while selecting if at least next histogram bar (or more) is less than selected limit:

Increasing the limit allows you to select more at once:

Else the range selection is free and limit will be hit as usual as you can see in the bottom bar:

ToDos:

• disable auto range selection when limit is reached at first step
• improve default query (range not selected) => keeping the default behavior and showing preview in the histogram for now
• show start / end as tooltips

Knowns bugs:

• can't select range from first click. You need to focus on another element (clic on Traffic flows tab for example) before selecting range
• histogram count mismatch summary count

Followups:

• implements hotkeys / buttons for next / previous 'page' using range steps
• tooltips while selecting range for better precision
