Add: Support for adding and removing Managed Identity records associated with a plugin assembly

[mkholt]

This pull request introduces support for managing "Managed Identity" records for plugin assemblies in Dataverse, including the ability to create, link, and remove managed identities via new sync commands. It adds new data models, service interfaces, and implementations to facilitate these operations, and updates the configuration and dependency injection to support the new identity sync functionality.

Managed Identity feature implementation:

• Added new entity model ManagedIdentity and related option sets (managedidentity_credentialsource, managedidentity_subjectscope) to represent managed identities in Dataverse. [1] [2] [3]
• Introduced IManagedIdentityReader and IManagedIdentityWriter interfaces, with corresponding implementations (ManagedIdentityReader, ManagedIdentityWriter) to handle reading, creating, linking, and removing managed identities for plugin assemblies. [1] [2] [3] [4]
• Registered new managed identity services in dependency injection (AddDataverseServices, AddIdentityService) for use in the application. [1] [2]

Sync command and configuration enhancements:

• Added new sync item and command options for identity operations (IdentitySyncItem, IdentityCommandOptions, IdentityOperation enum), and updated SyncItem type discrimination to support the new identity type. [1] [2] [3]
• Implemented IdentitySyncService to handle "Ensure" and "Remove" operations for managed identities, integrating with the new managed identity services and providing detailed logging and error handling.

Dataverse writer interface and implementation updates:

• Extended IDataverseWriter and its implementations to support entity deletion via a new Delete(Entity entity) method, enabling removal of managed identities. [1] [2] [3]

Pull request overview

Adds first-class support in XrmSync for creating/linking and removing Dataverse Managed Identity records for plugin assemblies, including a new CLI command and the necessary Dataverse models/read-write services.

Changes:

• Introduces identity sync/CLI command and configuration model (IdentitySyncItem, IdentityCommandOptions, IdentityOperation) plus validation and config parsing.
• Adds Dataverse managed identity entity + option sets, and reader/writer services to create/link/remove identities.
• Extends IDataverseWriter with Delete(Entity) and wires new services into DI; adds unit tests for identity sync and config/validation.
