Speaker pod fails to announce service if ExternalTrafficPolicy is changed to Local

Problem

• Speaker pod fails to announce service if ExternalTrafficPolicy is changed to Local.
• This happens only for a speaker pod running on a specific node of the cluster.

Environment

• Platform9 Managed Kubernetes - v5.4.0
• Kubernetes version v1.21
• Cluster with MetalLB

Cause

• If MetalLB is deployed with l2advertisement feature, then corresponding label is needed on the node.

Resolution

• Apply correct label on the node which is used for l2advertisement feature.
