Title: Merge duplicated --tcp option help text for lxd command

I found `lxd -h` prints `--tcp` option help text twice like below:

```
Usage: lxd [options]

Options:

--tcp
Bind to addr:port.
--debug (= false)
Enables debug mode.
--tcp (= "")
TCP address to listen on in addition to the unix socket
-v (= false)
Enables verbose mode.
```

With this pull request, it becomes like:

```
Usage: lxd [options]

Options:
--debug (= false)
Enables debug mode.
--tcp (= "")
TCP address to listen on in addition to the unix socket (e.g., 127.0.0.1:443)
-v (= false)
Enables verbose mode.
```
