/*
Create an initial query to retrieve a VNF Resource definition (including a list of possible module types)
within the context of a given service. Input is a vnf resource model customization ID (new field for 1702),
or a composite key (from 1610) of service name, service version, vnf instance name

Returns a structure (JSON?) containing VNF RESOURCE attributes, plus a list of VF Module structures.

Query a NETWORK_RESOURCE from the MSO Catalog, based on a networkModelCustomizationUUID (new for 1702),
a network type (unique type identifier in 1610), or based on network role within a service.

Create Adapter framework for access to Catalog DB, including connection management,
login/password access, transaction logic, etc. This can be modeled after the Request DB Adapter

Update the MSO Catalog DB schema to include the new fields defined in this user story.

Note that the resourceModelCustomizationUUID (or vfModuleModelCustomizationUUID) will be unique keys (indexes)
on the VNF_RESOURCE and VF_MODULE tables respectively.
The previously constructed "vnf-type" and "vf-module-type" field may continue to be populated,
but should no longer be needed and can deprecate in future release.

For migration, a new randomly generated UUID field may be generated for the *ModelCustomizationUUID" fields
until such time that the model is redistributed from ASDC.

All other fields Check with Mike Z for appropriate value for the vfModuleLabel.
We might be able to derive it's value from the current vnf-type (using the "middle" piece that identifies the module type).

min and initial counts can be 0. max can be null to indicate no maximum.

Once the network-level distribution artifacts are defined, similar updates can be made to the NETWORK_RESOURCE table.
