Allow guards to be dynamically enabled/disabled
Modified drools-apps so that guards can be dynamically enabled and disabled. Due to the current design, there are two properties that control this: - an actor-level property: when enabled, the DB connection is created, otherwise a stub connection is created. This property is NOT dynamic - an engine-level property: when enabled, the connection created by the actor is used, otherwise a stub connection is used. This property IS dynamic Issue-ID: POLICY-2748 Change-Id: I2a5baf908ce274f2eb46a6a3f01df1b3532038ff Signed-off-by: Jim Hahn <jrh3@att.com>
