Correct documentation and testcase data for some user-data YAML (#618)

For cc_users_groups the user setting "expiredate" must be quoted in
order for the relevant flag and value to be then passed to the useradd
command. It its vaiue is not quoted then it is treated as Python type
datetime.date and in `cloudinit/distros/__init__.py` the below "is it a
string" condition fails and so no "--expiredate" parameter is passed to
useradd and therefore it has no effect:

```
if key in useradd_opts and val and isinstance(val, str):
    useradd_cmd.extend([useradd_opts[key], val])
```

For cc_users_groups, the user setting "inactive" does not actually
disable accounts, the useradd "--inactive" option actually defines the
number of days after password expiry that users can still login. So I
have changed the docs to show it taking a quoted value of days (which
works with the current code) rather than a boolean value.  The quotes
are necessary, like expiredate above, so that the value is also passed
to the useradd command.

For cc_power_state_change.py the "delay" setting value needs to have
quotes around it as otherwise its leading plus sign will be stripped
off.
