I placed utils inside the components library due to extensive issues with referencing imports outside of this directory via aliases or relative paths.
Depending on what you choose I ran into issues with:

• Building extensions
• Building storybook
• Running storybook
• Importing into shell

I think that this is fine as long we intend to keep these utils internal to Rancher Components.

I left a few comments. I think the only item that we really need to address is the type casting.

I think this looks excellent and I hope that it will help to make our icon usage more consistent across the board.
