Style option for advanced pack filters and buttons

[Kharg]

Hello,

The option to create filters (using report filters) and buttons using advanced pack is really great but it’s missing one thing, the option to style them from the UI.

As of now styles for buttons and filters have to be added manually by editing the metadata, it would be nice if you could apply apply the style to buttons and filters: “default, primary, warning, danger, info”. using the UI.
