A class to store Session related configuration. It must be used at session instantiation time
or not used at all.
This class will automatically load default values from a number of places, accumulating properties from each location.
This list of locations, in given priority is:
System properties, home directory, working directory, META-INF/ of optionally provided classLoader
META-INF/ of Thread.currentThread().getContextClassLoader() and META-INF/ of ClassLoader.getSystemClassLoader()
So if you want to set a default configuration value for all your new KieSession, you can simply set the property as
a System property.
After the KieSession is created, it makes the configuration immutable and there is no way to make it
mutable again. This is to avoid inconsistent behaviour inside KieSession.
