NewDurationFromArg returns a time.Duration from a configuration argument
(string) which has come from the Corefile. The argument has some basic
validation applied before returning a time.Duration. If the argument has no
time unit specified and is numeric the argument will be treated as seconds
rather than GO's default of nanoseconds.
