Couchbase Mobile: Support for User Defined/ System Scopes & Collections

PRD: https://docs.google.com/document/d/1JEeAn_BO6ZbsIhOlT4WpRj3xwJnCot606nZZuG0_CLY/edit#

Scopes and Collections is integral part of how data is modeled in Couchbase Server v7.0+. End-to-end platform support is critical.  Lack of compatibility implies that App Services deployments cannot adopt scopes and collections functionality in Capella server. It also implies that existing server deployments on Capella (& on-prem) cannot expand into mobile without remodeling data. This is a major barrier in adoption of Couchbase across Capella and on-prem deployments

Support for scopes and collections will allow application developers to organize and logically isolate data.  

The ability to enforce independent lifecycle management and fine grained security control will simplify the deployment of multi-tenant and high-application density cloud-to-edge applications at scale. 

This ticket is to track customer  interest in supporting collections for mobile enabled deployments. For each ticket, please include details of the use case.
