Get pylint to understand async init and Parameters

[MarcusZuber]

Pylint has some problems with our code:

• pylint complains about creation of members outside if the constructor. This happens for all members of AsyncObjects, since we declare them in __ainit__ and not in __init__.

• pylint does not understand the installation of the get_ and set_ function of the Parameters. Therefore, it complains for all (async) parameter accesses with a no-member error.

I did't see a simple fix (beside deactivating all no-member and attribute-defined-outside-init errors/warnings) in the pylint configs.

Maybe anybody has a clever idea.
