Proxy options get removed in cda client

[rustyy]

Issue

With the option deliveryToken only published entries are supposed to be exported.

This fails if the request is executed behind a proxy.
The following code will fail:

import contentful from "contentful-export";

const options = {
    spaceId: "<space-id>",
    managementToken: "<my-cma-token",
    deliveryToken: "<my-delivery-token>",
}

contentful(options)
    .then((result:any) => {
        // ...
    })
    .catch((err:any) => {
        // A request fails if deliveryToken is given and a request is executed behind a proxy
    })

In the index.js the CDA-client is created via initClient(...).

The initClient function is not aware of all options given and remove possible proxy options passed in by the consumer.

In result the contentful-export fails if used behind a proxy.

Expected behavior

Given proxy-settings should be taken into account if passed in by the consumer together with the deliveryToken.

@rustyy Thank you for bringing this to our attention. I agree we should be doing this. I added an item to our backlog to address this but I don't have a current estimate of when we will get to it
