Fix issue #316: New component for Medicina K band receivers (#318)

* working issue #316: the SRT component for the K band receiver has been adapted for Medicina one. The Reciever are, in theroy, identical from the control
point of view. In order to do that SRT interface has been ported into Medicina. The component has been split into two main parts, a part contains code that could be shared and has been put in the Common repository, the other one has been implemented on both lines. Also component configuration has been duplicated. Some work still necessary as the readouts in Medicina still do not match the expected. Probably a check of how the values maps into digital I/O is needed.

* fixed he readout for Medicina K band Receivers. Control of the local oscllator still missing.
The receivers boss component must be modified accordingly.

* fix issue 316: Added python component to control the Medicina synthetiser. Also is configuration and functiona tests added.

* fix issue #316: Medicina KKc configuration done. Also the Receivers Boss has been changed in order to rely on the new KKC MF component for
all the K-band relatad operations.
This closes the issue. Some tests needed though.
