Public bug reported:

https://netplan.io/reference/ supports wifi password and auto client-
key-password keys which should generally not be world-readable.


But, when rendering passthrough V2 network configuration, cloud-init emits a single /etc/netplan/50-cloud-init.yaml file that is world readable.

If network v2 config contains sensitive password keys it may make sense
for cloud-init to either:

1. Make /etc/netplan/50-cloud-init.yaml only root-readable
- OR -
2. Write a world-readable /etc/netplan/50-cloud-init.yaml containing all keys except wifis and auth  and a root-readable /etc/netplan/50-cloud-init-sensitive.yaml  which would contain any security sensitive config content.
