How to add a new icon

• Add the new icon svg to the unicons/ directory
  • Yes, even if it's not a unicon icon or from IconScout
  • We will eventually condense all the separate folders into a single icons/ directory, and since unicons/ is the default it makes sense to add new icons there
• Add the new icon path to public/app/core/icons/cached.json
• Ensure the new icon source is formatted correctly:
  • Remove any width or height attributes
  • If the icon is a single color, ensure any explicitly defined fill or stroke colors are either removed (or set to currentColor if a color must be defined)
    • This allows the consumer to control the color of the Icon, which is useful for hover/focus states
• Modify the availableIconsIndex map in @grafana/data and add the new icon
  • Note: the key must exactly match the icon filename, e.g. if your new icon is my-icon.svg, the key must be my-icon
• Run yarn storybook and verify the new icon appears correctly in the Icon story
