In this patch, multiple failures in VNF lifecycle such as Scale, Rollback and Heal are fixed. The fixed cases are the following: - It cannot set correct value to operation_params due to the lack of parameter setting in sending Notification. - 409 error occurs due to incorrect STATUS setting in Rollback. - Scale fails since instance_id/aspect_id cannot be set correctly. - HOT creation in Scale fails since API information cannot be set correctly. - In the case including recreating stack such as Heal, a waiting process fails due to un-updated instance_id. - Scale/Rollback fail since instance_id cannot be held during Instantiation. - Rollback fails due to incorrect state holding during Instantiation. - Uploading package in separate mode fails due to incorrect package extraction. Additionally, the following modifications are also done. - instance_id setting process is enhanced. - Mismatches of definition in some arguments are resolved. - Incorrectly merged code into the master is fixed. - Setting of STATUS name during Rollback is fixed. - Mock is added due to the modification of this patch. - Definition of column in DB migration is fixed.
