Include method being retried

Description

The RETRY decorator currently shows a message:

Retry 2/15 after 5.000000 seconds...

However, it would be good to include in this info message which method is being retried so that we can track what is the issue.

Demo or definition of done

Upon having a retry, the message should be, for instance:

Retry [DeviceClient:AddDevice] 2/15 after 5.000000 seconds...

Alternatively, we could add a parameter e.g. verbose where the info message would also include a JSON representation of the input parameters. For instance:

Retry [DeviceClient:AddDevice(parameters here)] 2/15 after 5.000000 seconds...

Draft of a solution

In order to show the class and method being retried, we can include the following code in the decorator definition:

python LOGGER.info('Retry [{}.{}] {:d}/{:d} after {:f} seconds...'.format(func.__module__, func.__name__, num_try, max_retries, delay))
