Make targetEntity a property

Make targetEntity a property

The target entity is not always known when an Operation is first
constructed, thus it should be treated as an Operation property instead
of being included within the ControlLoopParams.  Started the process of
moving it from the Params to the properties.
Also fixed a bug in custom query - it was setting the outcome response
to the String response instead of setting it to the AaiCqResponse
object.
Also added logging when an Operation's properties are set.
