The DBus interface needs to be specified in an XML file using the "Introspection Data Format".
A PoC of how our interface could look like can be found at: https://github.com/lluiscampos/mender/blob/prototype-dbus-api-docs/spec/AuthenticationManager1.xml
- The spec file is added
- The methods and signals in MEN-4007 are documented
- Doxygen style comments are used to describe parameters, summary, etc.
