Add 'DroolsRunnable' class
This provides a simple way to run arbitrary Java code within the Drools thread. This change also includes a general way to specify Drools rules that are automatically added to every Drools session. Change-Id: I5ddcca4c807dc552fbcbd4a19dce311a4d358279 Issue-ID: POLICY-1948 Signed-off-by: Straubs, Ralph (rs8887) <rs8887@att.com>
