As an SDC TOSCA Model consumer I would like the TOSCA Model to include the following enhancements for the Tenant Isolation context:

Overview:
Overall goal: to be able to run revenue and non-revenue (e.g., test) regular tenants (e.g., VNFs)  and platform tenants (ECOMP components) on production AIC.  The solution here is to have new metadata attributes that describe the environment type (e.g, Production, Test, Development), Tenant Type (e.g., Revenue, Non-revenue) and so on that are used to drive the isolation needed to manage and safely run these workloads on the production cloud.  These new metadata attributes are termed as “Tenant Isolation Context”. Tenant Isolation

The Isolated Context is the combination of the three context values:
·        Environment = Where should I deploy                         = General_Revenue-Bearing
·        Tenant = For whom will the deployed service be for    = Test
·        Workload = Why do I need to deploy                           = E2E-SIT

Tenant Type: Defined by SSP, value provided to A&AI via RO during "Tenant Creation", selected by VID or Homing from A&AI as part of instantiation

Environment context: shall be populated in design time and shall not be modified during instantiation (New service metadata field)
Workload Context:  Wןill be provided part of the SDC distribution event and will always be provided with  the "Production" workload context value.
In phase 1 (E1802) VID will not modify the value provided in  the model
In phase 2 (1802) OPS user will be asked to provide production workload context from a pre-defined list of values, to be populated in the distribution event.

Acceptance criteria:

• Environment new meta data field is part of service generic information UI
• Environment is exported in TOSCA for servie with conformance level 5 and up
