*To scale down API Gateway
1. Remove a node from the cluster by performing the following steps:
a. Enable the Quiesce mode in the node that you want to remove. The node will stop accepting transactions requests, and the Load balancer routes the requests to other nodes.
b. Shutdown the node after a grace period to allow ongoing requests to complete. The period depends on the responsiveness of the native services and the timeout setting for outbound requests. The timeout for outbound requests is defined via watt.net.timeout configuration parameter
c. Remove the node from the Load balancer.
The node is removed.
