Created by: vovakulikov

This PR adds a new chart component - the bar chart. This chart represents categorical-like data (it's different from series-like data where the x-axis acts as a timeframe, in categorical-like data x-axis is a set of different categories)
| Chart type | Example |
|---|---|
| Regular categories |  |
| Categories with sub groups |  |
| Categories with stacked groups |  |
This component also reuses the tooltip that we implemented during the line chart development.
A few things to notice that are not implemented/covered by this PR
- This PR doesn't add a new bar chart for series-like (through time) data
- This PR's bar chart doesn't cover all corner cases around label positioning
Test plan
- Make sure that the chart has the right Y/X labels and correctly represents data sets in storybook stories
- Make sure that the tooltip works correctly in all modern browsers (Firefox, Safari, Chrome)
