Duplicated logs with default logging config

[Pafnut]

There are duplicated logs records in cloud-init logs with default logging configuration.

Default logging configuration is used (via tee)

output: { all: "| tee -a /var/log/cloudinit/cloudinit.log" }

In the attached cloudinit.log duplicated logs starts from line 314:

WARN: no logging configured! (tried 0 configs)

What you expected to happen: No duplicated logs with default logging config

What happened instead: Duplicated log records with default logging

Hi,
Your cloud.cfg that is attached differs from the version provided in 16.04, or upstream.
normally you'd find the following in /etc/cloud/cloud.cfg.d/05_logging.cfg:

   output: {all: '| tee -a /var/log/cloud-init-output.log'}

So it looks like local configuration is just incorrect. Please set bug to New aain if you think i've diagnosed this wrong.
