Derive service settings from hosts definition

[Vladislav Staroselskiy]

This helped a lot - thank you both for explanations! I saw this link earlier, but somehow missed "implied inheritance" part of it.

Also keep in mind you can use user defined host based macros that can
be defined in the templates to make parameters to the service checks
inherited from the host as well. I used this feature to create classes
of hosts while at the same time giving me the option to tweak the
thresholds on a class-by-class or host-by-host basis. Very flexible.
