[Haizea] documentation on trace file

Specifying an "unlimited" duration is only supported in the RPC
interface and, as you can tell, it is really just a kluge because it
gets translated to requesting a lease for a 100 years. So, there is no
way of specifying an unlimited duration lease in XML, other than
requesting an arbitrarily long duration. The only problem I can think
of is that you would have to make sure to also include a premature
ending time (with <realduration>). Otherwise, it will be hard to
interpret the data collected during a simulation because there would
be 100-year leases in it :-)

This is something I definitely want to change (since it does make
sense to distinguish unlimited durations from arbitrarily long ones),
but is currently not too high on my TODO list.

Cheers!
