Lack of any return message on command that required admin privs

[Brad Figg]

I'm using MAAS 2.9.2 cli. I encountered several possible issues when trying to add a tag to a machine. I'm not sure any of these are truly bugs but I'll specify them anyway:

1. I was logged in as a MAAS user (jenkins) and not an admin and ran the command 'maas jenkins tags create name=bjf comment=bjf". Nothing was returned. However, when I ran 'maas jenkins tags read' I did not see a tag named 'bjf'. I re-logged in as a MAAS admin (bradf) and tried again and this time I got back a message that indicated it had succeeded and 'maas bradf tags read' listed it among all the other tags.

2. I started this by going to the link: https://maas.io/docs/snap/2.9/cli/how-to-use-machine-tags#heading--assign-machine-tags-to-a-machine . This does not mention that first a tag must be created before being assigned to a machine. I assumed that simply running the command to assign a tag created the tag on for the given machine. I think it would be helpful if this was more clearly spelled out with a pointer to the documentation on creating a tag.

3. When I ran the command "maas jenkins tag update-nodes add=xxxxx" what I got back was "Not Found". It would have been helpful if it said "Tag not found".

Another point of confusion was:

4. Running maas $PROFILE tag --help includes the following:

...
    update-nodes Add or remove nodes by tag
...

This seems to suggest that the nodes will be added or removed rather than the tags.
