Goal
We find it necessary to get rid of ant.design library for the following reasons:

1/ Substantial library size which has an impact on the bundle size. Moreover, we only a select number of its components.

2/ Opinionated styling system. We end up overriding antd styles which are not compatible with grafana's.

3/ Most of the components can be easily replaces with either @grafana/ui components or our own.

The tickets of this epic address the problem, component by component.
