Support for distributed Voca CIC services

Live Platform now supports the management of multiple Voca CIC devices within a single deployment. Previously, Voca CIC was installed and operated as an external application. This enhancement includes a new entity "Network Tenant" created for the purpose of this feature. A Network Tenant represents a Voca CIC sub‑region and can be associated with either a Service Provider tenant or a Channel tenant. A managing tenant may have multiple sub‑regions attached to it. When adding a Voca CIC service, you first select the relevant customer and then choose the appropriate sub‑region. The available sub‑region options are limited to those that are already attached to the managing tenant.
