[joshrotenberg]

Summary

Implement Private Service Connect (PSC) commands for network connectivity operations in the Cloud API.

Parent Issue: #120

Scope

This is Part 2 of 3 for implementing connectivity commands. This issue covers Private Service Connect only.

Commands to Implement

Standard PSC Service & Endpoints (9 commands)

• Get PSC Service: psc get-service --subscription ID
• Create PSC Service: psc create-service --subscription ID
• Delete PSC Service: psc delete-service --subscription ID
• List PSC Endpoints: psc list-endpoints --subscription ID
• Create PSC Endpoint: psc create-endpoint --subscription ID [OPTIONS]
• Update PSC Endpoint: psc update-endpoint --subscription ID --endpoint-id ID
• Delete PSC Endpoint: psc delete-endpoint --subscription ID --endpoint-id ID
• Get PSC Creation Script: psc get-creation-script --subscription ID --endpoint-id ID
• Get PSC Deletion Script: psc get-deletion-script --subscription ID --endpoint-id ID

Active-Active PSC Service & Endpoints (9 commands)

• Get AA PSC Service: psc get-service-aa --subscription ID
• Create AA PSC Service: psc create-service-aa --subscription ID
• Delete AA PSC Service: psc delete-service-aa --subscription ID
• List AA PSC Endpoints: psc list-endpoints-aa --subscription ID
• Create AA PSC Endpoint: psc create-endpoint-aa --subscription ID [OPTIONS]
• Update AA PSC Endpoint: psc update-endpoint-aa --subscription ID --endpoint-id ID
• Delete AA PSC Endpoint: psc delete-endpoint-aa --subscription ID --endpoint-id ID
• Get AA PSC Creation Script: psc get-creation-script-aa --subscription ID --endpoint-id ID
• Get AA PSC Deletion Script: psc get-deletion-script-aa --subscription ID --endpoint-id ID

Special Considerations

• Scripts (creation/deletion) should be output as plain text, not formatted
• PSC requires specific cloud provider configurations
• Endpoints may have complex networking requirements
