regs: Add manager object

Create a manager object that extends the manager interface overriding
the configure and monitor methods. This provides the framework for
receiving dbus method calls at the appropriate times during a system
poweron or poweroff.

Tested:
    Used `busctl` to call the configure method
    Used `busctl` to call the monitor method
