From the client point of view, three methods of the host object are of
interest. By calling the :available method of a host object,
it returns a boolean indicating whether it considers itself available
for additional jobs or not. The :relative-load method returns
a performance adjusted metric of the hosts load which can be used for
load balancing. And finally, the :execute method launches a
task on a host, which actually means that a remote process is started.
