4.2.1 changes fix some issues around supporting OsContainer based VNFs

Changes from v4.1.1

New Classes/Types:

  1. New Class  VirtualCpd.  New datatypes AdditionalServiceData and ServicePortData 

Other changes:

  1. New property vnfd::osContainerDesc of type OsContainerDesc with cardinality 0..N which defines descriptors of container compute resources to be used by the VNF when the VDUs of the VNF are realized by a set of OS Containers sharing the same host and same networking namespace.  Only one of virtualComputeDesc or osContanerDesc may be present in the vnfd
  2. New property vnfd::virtualCpd which describes a virtual connection point(s) allowing to access a set of VNFC instances (based on their respective VDUs).
  3. New property VnfExtCpd::virtualCpd which references the Virtual CPD which is used to describe a virtual connection point allowing to access a set of VNFC instances (based on their respective VDUs). 
  4. New property vdu::osContainerDesc of type identifier (Reference to osContainerDesc) with cardinality 0..N which describes CPU, memory requirements and limits, and software images of the OS Containers realizing this Vdu corresponding to OS Containers sharing the same host and same network namespace. Each unique identifier is referenced only once within one VDU.
  5. Modification of VduCpd::vnictype to include several new types (BRIDGE, IPVLAN, LOOPBACK, MACVLAN, PTP, VLAN, HOST-DEVICE)
  6. Modification to the cardinality of SwImageDesc::diskFormat, SwImageDesc::minDisk to allow cardinality of 0..N
  7. New property VndDf::mciopProfile of type mciopProfile with cardinality 0..N which describes additional instantiation data for the MCIOPs used in this deployment flavour. This attribute shall be present if the DF references containerized workloads based on a MCIOP.
  8. New property VirtualStorageDesc::volumeTemplate of type Boolean with cardinality 0..1 which indicates whether the virtual storage descriptor shall be used as template, i.e. if the virtual storage resource shall be instantiated per VNFC instance. If the value is true (default), a persistent virtual storage resource shall be instantiated for each VNFC instance that is based on a VDU referring to this virtual storage descriptor. If the value is false, a single persistent virtual storage resource shall be instantiated with a lifetime independent of the lifetime of individual VNFC instances based on a VDU referring to this virtual storage descriptor.
