GateControlList parameters are mutable but handleParameterChange is not implemented

[haug-den-lucas]

As stated in the title, the parameters of a GateControlList are marked as @mutable which suggests that these parameters can be changed during runtime:

https://github.com/inet-framework/inet/blob/ce08305b86ddff9534e870ccd1aa913553d50c56/src/inet/queueing/gate/GateControlList.ned#L17-L18

However, parameter changes are ignored, so either:

• The parameters should not be marked as mutable
• handleParameterChange should be implemented
