HazelcastInstanceFactory can't instantiate custom IHazelcastInstanceLoader

[jontejj]

java.util.Properties requires values to be strings. So (IHazelcastInstanceLoader) props.get(...) does not work. Better to treat it as a class name and instantiate the factory instead.

Hi @jontejj,
It is intended to be used as part of the tests, hence not documented and for internal use only. What is your use case for this, do you want to customise instance loading process?

[jontejj]

We want to integrate overwriting some of the config before loading the instance. For example specifying ip:s for members in the cluster for different environments. We don't want to duplicate the config for three different environments.

I see now that we can use .put instead of setProperty :).

[jontejj]

Reopening this as we ran into issues with a property being a non-string. For the sake of integrating with other libraries it's better to use best practises and not store non-strings in the properties.

I was a bit unfamiliar with how pull requests works in github, so I'll create a PR for this when #22 has been merged.
