Clear IAM role from config

[holmesjr]

It would be nice to have a CLI option to clear the saved IAM role from the config, so we could swap between roles without having to edit the config file manually. I can send a pull request if you're happy to consider the change.

There is the reset command. I use reset to completely wipeout the specific aws profile. Would you like to describe the usage scenario, you have in mind, so the need would be clearer for me?

Ah, my mistake. I used the default profile in my auth but then reset without specifying a profile (so it defaulted to adfs).

Perhaps I should improve the description. If you have any suggestion on that I would be glad 😄

Happy that it was PEBKAC over here.
