Juju 2.7-rc2, --client-only flag not implemented in add-k8s

[🤖 prod-jenkaas-charmed-osm]

Hello,

I am testing the juju 2.7-rc2 snap, and I found an issue:

First of all, if I add the k8s cloud with the following command, it doesn't work:

davigar15@Canonical:~/osm-dress-rehearshal$ microk8s.config | juju add-k8s k8s
This operation can be applied to both a copy on this client and to the one on a controller.
Do you want to add k8s cloud k8s to:
    1. client only (--client)
    2. controller "aws-osm-ha" only (--controller aws-osm-ha)
    3. both (--client --controller aws-osm-ha)
Enter your choice, or type Q|q to quit: ERROR EOF

With the --local flag it works, BUT, in the `juju add-k8s --help` command, it shows that the --local is deprecated:

```
--local (= false)
    DEPRECATED (use --client-only): Local operation only; controller not affected
```

It says to use --client-only instead, and this is what happens when doing that:
```
davigar15@Canonical:~/osm-dress-rehearshal$ microk8s.config | juju add-k8s k8s --client-only
ERROR option provided but not defined: --client-only
```

Using --client instead of --client-only is working:
```
davigar15@Canonical:~/osm-dress-rehearshal$ microk8s.config | juju add-k8s k8s --client

k8s substrate "microk8s/localhost" added as cloud "k8s".
You can now bootstrap to this cloud by running 'juju bootstrap k8s'.
```

I don't know if it is an issue in the help of the add-k8s, or an alias is missing.

Thanks,
David

Ups, it was me @davigar15

This is a typo in the help text for the deprecated --local option.

--client is what's required

(not --client-only)
