Dispatches an activity to the SPF instances matching the given
identifier. The framework will perform information injection into the
activity: such information will be available to the caller once the
method ends.

@param target
- the target of the activity.
@param activity
- the activity to dispatch.
@return - true if the activity has been correctly consumed by the
recipient.
