Kombu shouldn't depend on requests

[gopackgo90]

Kombu pre-release now depends on requests, which now will get installed on systems that install celery, which isn't desirable. I understand that the restriction was added in eae7585 to work around a bug for your CI, but that should not be done in a place that impacts user installations.

Kombu pre-release now depends on requests, which now will get installed on systems that install celery, which isn't desirable.

Your argument is valid, IMHO. Our CI “issues" should not change the product’s dependencies just to satisfy the tests.
See #2041 for motivation to close this issue.
