This change includes the BusProvider import in the `__init__.py` file of
dbus_middleware1. It ensures the module has access to BusProvider
functionality, improving modularity and readiness for use.
Consolidated `REVPI_DBUS_*` constants and `extend_interface` function
into `dbus_helper.py` for better modularity and reusability. Updated
imports across modules to reflect this change.
This function constructs a fully qualified interface name by appending
segments to a predefined base name. It simplifies and standardizes the
process of generating extended interface names in the middleware.
Introduce a D-Bus middleware module for revpi_middleware, including an
interface definition and a `BusProvider` class to handle D-Bus
communication. This forms the foundation for middleware interactions
using D-Bus.
