auro-badge: set icon color from badge

[braven112]

Is your feature request related to a problem? Please describe.

The lounge team would like a Club 49 badge. Very similar to the existing oneworld, lounge, and mileage plan badge but with an icon included.

Describe the solution you'd like

Ideally a user can follow the same process that we have established for oneworld, lounge and mileage plan badges and style the icon by the same auro-badge attribute. Currently a user can achieve this using a custom badge but they would also need to customize the icon color to match because the icon is not included in the badge repo.

Describe alternatives you've considered

• Lounge teams builds a web component in the component hangar for 'Guest badges' that is just a wrapper that implements standard auro-badge customizations for our Alaska tier badges, oneworld tier badges, Club 49 badge(new) , Lounge & Lounge+
