Incorrect example in the 'add locationFile' command

### The example in the add locationFile command is wrong, it does contradicts the description of the 'format' flag and it just doesn't work

'Citrix ADC' is not a valid value for the 'format' flag (it is not in the list of allowed values, as this very same document states).

```
> add locationfile /var/nsmap/locationdb -format Citrix ADC
^^^^^^
ERROR: Invalid argument value [Citrix]
>
```
