Azure Communication Identity Client

The `azure-communication-identity` library provides client-side functionality for managing user identities and issuing access tokens for Azure Communication Services. It allows applications to create, delete, and manage users, and to generate tokens required for client-side authentication with various communication functionalities like chat and calling. The current version is 1.5.0, and new versions are released regularly as part of the broader Azure SDK for Python, typically every 1-2 months or as features/fixes dictate.
