b8f3318ca6
Implements the foundational infrastructure for a new standalone networking service that can operate independently of the main ironic conductor. This commit establishes the service skeleton with: - RPC API layer with oslo.messaging integration for remote calls - Public API interface for conductor/API to interact with the service - RPC service implementation for handling network requests - Stub networking manager with method signatures (implementation added in subsequent commit) - Service entry point (ironic-networking command) for deployment - Configuration options for service behavior and networking backend - Infrastructure and packaging changes for the new service The manager includes stub implementations that raise NetworkError, with the full implementation of network operations, driver framework and switch drivers are added in subsequence commits.
