disconnected interface not set to optional in netplan config

[Dylan Wang]

recently I found our servers stuck 2 mins after boot due to:

"A start job is running for Wait for Network to be Configured."

according to https://askubuntu.com/questions/1090631/start-job-is-running-for-wait-for-network-to-be-configured-ubuntu-server-18-04

set the disconnected interface to optional fix this issue.

I think netplan template need update, this slow down everyone's boot time.

Please check the attacked logs below, and the resulting netplan config is:
