build: move e2e dependencies into e2e/go.mod

Several packages are only used while running the e2e suite. These
packages are less important to update, as the they can not influence the
final executable that is part of the Ceph-CSI container-image.

By moving these dependencies out of the main Ceph-CSI go.mod, it is
easier to identify if a reported CVE affects Ceph-CSI, or only the
testing (like most of the Kubernetes CVEs).

+Package baggage provides base types and functionality to store and retrieve

+OpenTelemetry needs to synchronize state whenever baggage for a context is
+modified and that context contains an OpenTracing span. If it were not for
+this need this package would not need to exist and the
+`go.opentelemetry.io/otel/baggage` package would be the singular place where
