PASE Commissioner (#982)
* getter change and code simplify
* Enhance Commissioner
Enhance the "doOperationalDeviceConnection" callback with the option to notify the commissioner that the completion of the commissioning process was done via other ways (e.g. from a server differently from the commissioner instance).
* Enhance/Streamline CommissioningController
The commisioning options got an optional callback to allow custom commissioning completion ways.
Additionally streamline the interface (breaking) to allow just to commission to a device without a connection afterwards.
* Enhance RootCertificateManager init
And allow the class to be initialized with data and without storage too.
* Split out Env options from Controller to own type
* Move NatterController to options constructor
* Adjust Controller to generally work also without IP network
... but the standard "create" is still requiring it, so external interface stays unchanged
* No custom commissioning-complete for standard controller
... because makes no sense for now.
* Introduces StubCommissioner
This class is a minimalistic commissioning controller that allows to just execute the initial commissioning process without completion. For this it gets initialized with the Root certificate data and the fabric data from a Controller fabric that already exists. A callback is called when operational discovery and completing the commissioning is needed.
* Allows custom commissioning completion
* Better name PASECommissioner
* Changelog
* Changelog
* linter fix
* exposes data for initialization of PaseCommissioner
