Subject: [PATCH] Fix help message for memory-swap

Back quotes are the placeholder feature described here:
https://github.com/urfave/cli#placeholder-values

Without this, cli will take `-1` as default value as:
```
   --memory-swap -1             Total memory usage (memory + swap); set `-1` to enable unlimited swap
```

After this patch, it'll act correctly
```
   --memory-swap value          Total memory usage (memory + swap); set '-1' to enable unlimited swap
```
