chore: Reuse AI Foundry Project

[Shreyas-Microsoft]

Purpose

This pull request introduces several enhancements and updates to the infra Bicep files, primarily focusing on support for existing AI projects, improved resource configurations, and the addition of a new module for Key Vault secret management. Below is a summary of the most important changes grouped by theme.

Support for Existing AI Projects:

• Added a new parameter azureExistingAIProjectResourceId to allow reuse of an existing AI project resource ID in infra/main.bicep and infra/main.parameters.json. [1] [2]
• Updated the aiServices module to include configurations for reusing existing AI project resources, such as existingFoundryProjectResourceId, and added new properties like disableLocalAuth and allowProjectManagement.
• Modified infra/modules/ai-foundry/project.bicep to conditionally create a new AI project or reference an existing one based on the azureExistingAIProjectResourceId parameter. Outputs now include metadata for the AI project. [1] [2]

Resource Configuration Updates:

• Changed the name format for the aiServices module to align with the naming conventions for Cognitive Services accounts.
• Updated role assignments in the keyVault module to use the Key Vault Administrator role instead of Key Vault Reader and adjusted the principal ID logic.
• Updated environment variables in the containerAppBackend module to use aiProjectInfo outputs for better alignment with the new AI project structure. [1] [2]

New Module for Key Vault Secret Management:

• Added a new module keyVaultExport.bicep for managing Key Vault secrets, including parameters for secret configuration and outputs for secret references.

Documentation Fix:

• Fixed a minor typo in infra/samples/network_subnet_design.md to correct the formatting of a file reference.
