Add a __getitem__ method to VIVirtualMachine class

[GoogleCodeExporter]

This is an enhancement proposal. It would be fantastic if we could add a 
__getitem__ method to VIVirtualMachine classes so that one might be able to 
index a VIVirtualMachine instance—like so: vm['memory_mb']—and get the 
pertinent information. This would essentially be a shorthand for the following:
``
vm.get_properties()['memory_mb']
``

Note that there's an optional parameter in properties from_cache which makes it 
impossible to be *replaced* by something like this. Imo it's not a good thing 
to have two obvious ways to get exactly the same information.
