log-opts are passed to logging-drivers as-is, so the daemon is not
aware what value-type each option takes.
For this reason, all options must be provided as a string, even if
they are used as numeric values by the logging driver.
For example, to pass the "max-file" option to the default (json-file)
logging driver, this value has to be passed as a string;
```json
{
"log-driver": "json-file",
"log-opts": {
"max-size": "10m",
"max-file": "3"
}
}
```
When passed as a _number_ (`"max-file": 3`), the daemon will invalidate
the configuration file, and fail to start;
unable to configure the Docker daemon with file /etc/docker/daemon.json: json: cannot unmarshal number into Go value of type string
This patch adds an example to the daemon.json to show these values
have to be passed as strings.
