Feature: Provide easy way to clear the API token used by API Explorer
Description: There’s a set api token button:
Once used, something is set, somewhere. But there isn’t an obvious “Clear API Token” button.
Use-case: Once someone is done using the API explorer, it’s comforting to be able to discard the token. This is akin to “log in” and “log out”, but the system effectively only has a “log in”.
