Title: Add missing second (s) unit to units table

There is an implied missing metric unit of _seconds_ when defining the `rate` metric/target type:

```blockquote
rate: a number per second (implies that unit ends on '/s')
```

There are also other references to second too. This pull request simple adds the missing unit to the units table in the spec file.
