[Hawkular-dev] resource config and operations

[Lukas Krejci]

I am not 100% sure it is a good idea to store maps or other "rich" types as 
property values in inventory as that may have influence on their indexability 
or (altogether the ability to persist such objects).

There are for sure performance implications for doing so but we need to wait 
for those until we have Titan running in dist. The in-memory database we're 
using atm should be taken with a grain of salt for any supported features - 
for one - transactions are only simulated using locks and property values are 
just java-serialized.
