References and resources for building multi-tenant applications on Azure

UPDATE: In August 2021, we created a doc in the Azure Architecture Center with links to resources related to multitenancy. Please refer to the “Resources for architects and developers of multitenant solutions” page in the https://aka.ms/MultitenantArchitecture section.
