SimplePredicates have a configurable initial value that can be set to unknown or false. Previously, CombinationPredicates and MetricProducers were automatically initialized with an unknown condition value instead of being synced with the conditions of the SimplePredicates that they rely on. An initial condition cache is used to store initial conditions of ConditionTrackers after they are initialized. CombinationConditionTrackers evaluate their initial condition based on the initial conditions of their child SimpleConditionTrackers. MetricProducers also use the initial condition cache to set its condition during initialization. Added unit tests in SimpleConditionTracker_test to check that SimpleConditionTrackers have the correct initial conditions based on what the InitialValue is set to and the condition is updated properly after the first few condition change events. Added unit test in MetricsManager_test to check that all ConditionTrackers and MetricProducers have the correct initial conditions.
