Node 10 Lambda phase 1 support ends by July 30, 2021

[yzhanggithub]

There is a Node 10 lambda in the repo. It may cause issue to create (or update later) when Node 10 Lambda support ends in AWS.
Workaround if not updated in the release:
In env/dev/ecs-event-stream.tf, change the runtime to either value - "nodejs12.x" or "nodejs14.x"
