Code review comment for ~redriver/cloud-init:frbsd-azure-branch

I'm confused because Ubuntu's cloud.cfg is exactly what is in
config/cloud.cfg in trunk. which has:

     # This will affect which distro class gets used
     distro: ubuntu
     # Default user name + that default users groups (if added/used)
       name: ubuntu
       lock_passwd: True
       gecos: Ubuntu
       groups: [adm, audio, cdrom, dialout, dip, floppy, lxd, netdev, plugdev, sudo, video]
       sudo: ["ALL=(ALL) NOPASSWD:ALL"]

Thats almost identical to what config/cloud.cfg-freebsd has in your

I think that comment is actually wrong. If you look at how that method
works, it basically builds an array of configs (dictionaries), with
environment config (from environment CFG_ENV_NAME) first, then isntance
configs, then datasource, then base. Then calls mergemanydict with that.

So basically:
     {'foo': 'from enviroment'},
     {'foo': 'from instance, no user override'},
     {'system_info': {'default_user': {'name': 'smoser-from-ds'}}},
     {'system_info': {'default_user': {'name': 'ubuntu'}}},

Calling that returns:
{'foo': 'from enviroment',
 'system_info': {'default_user': {'name': 'smoser-from-ds'}}}

So I'm pretty sure the comment is just wrong. Its probably because
'mergemanydict' has very odd usage in that precedence goes to the *first*
value, not the last.
