SREP-3023 : Fix skipped LB reconciliation e2e test

[rpodishe]

Ticket - https://issues.redhat.com/browse/SREP-3023

• Add lbReconcileTimeout = 10 * time.Minute constant dedicated to the LB
  reconciliation test, leaving pollingDuration (2 min) unchanged for all
  other tests
• Remove ginkgo.Skip("skip test pending OSD-29874")
• Update 3 PollUntilContextTimeout calls in the LB test (1 AWS, 2 GCP) to
  use lbReconcileTimeout instead of pollingDuration
• Fix nil pointer dereference in GCP forwarding rule comparison: when oldLB
  is nil (forwarding rule already absent at test start), the comparison
  newLB.Name != oldLB.Name panics. Added oldLB == nil guard.
