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
