feat: add a way to provide an axios instance

[jdrouet]

When using the axios client, I'd like to be able to provide an axios instance. The way to do in the doc is to define a global constant which is then used globally. This is a problem because it allows only a single instance of the client in the application and it's potentially prone to security issues. With this, we can create an instance of axios an pass it as an argument like the following

const instance = axios.create({ headers: { Authentication: 'Bearer foo' } });
const api = createClient();

return api(instance);

Parameter 'axios' cannot reference itself.
