Logging polution

Many random print calls can be found throughout the code which pollutes the output logs at unexpected moments.

These are the ones I see when starting a lima simulator:

https://gitlab.esrf.fr/limagroup/Lima-tango-python/blob/master/LimaCCDs.py#L378

class LimaCCDs(PyTango.Device_4Impl):

    def __init__(self,*args) :
        PyTango.Device_4Impl.__init__(self,*args)
        ...
        print('YO')

https://gitlab.esrf.fr/limagroup/Lima-tango-python/blob/master/LimaCCDs.py#L2604

def export_ct_control(ct_map):
    ...
    print("Creating device {0}({1})...".format(tango_class_name, name))
    util.create_device(tango_class_name, name)
    print("Done")

https://gitlab.esrf.fr/limagroup/Lima-tango-python/blob/master/EnvHelper.py#L439

def create_tango_objects(ct_control, name_template):
    ...
    print("ctcontrol.{0}() = {1}".format(ct_func_name, getattr(tango_ct_control, ct_func_name)()))

https://gitlab.esrf.fr/limagroup/Lima-tango-python/blob/master/plugins/LiveViewer.py#L122

class LiveViewer (PyTango.Device_4Impl):

    def init_device(self):
        ...
        print ("Warning: setFrameRate() not supported")

Then for a lima simulator (different project):

https://gitlab.esrf.fr/limagroup/Lima-camera-simulator/blob/stable/tango/Simulator.py#L126

class Simulator(PyTango.Device_4Impl):

    def __getattr__(self,name) :
        print(name)
        print(type(_SimuCamera.getFrameGetter()))
