I think this is best served by 'herd stop', followed by 'herd 
start'. This patch just special-cases the 'restart' action, so 
manually stopping then starting a service will behave as the old 
restart used to.

Hopefully the above also answers this, too. I did consider whether 
it was worth adding a test for 'herd stop' to make sure it still 
stops dependent services, and 'herd start' to make sure it doesn't 
start dependent services, but in the end I decided not to. I'm 
happy to send through another patch to test these cases, though, 
if you think it would be worthwhile.
