Reduce level of many log messages

[aromanielloNTIA]

Reduces lots of info- and warning-level logs to debug level. Now, everything is debug level, except:

Error/Exception Level:

• When discover/__init__ is unable to determine the RSA model
• When hardware/__init__ is unable to initialize the signal analyzer interface, and sigan is set to None
• When the signal analyzer interface __init__ fails and sigan power cycling is triggered
• When an attempt is made to set the sampling rate to an invalid value (also raises ValueError)
• When an attempt is made to set the IQ bandwidth to an invalid value (also raises ValueError)
• When the signal analyzer interface connect() method fails to find and/or connect to the signal analyzer (also raises an exception)
• When the tekrsa-api-wrap API wrapper cannot be loaded and the signal analyzer is disabled (also raises ImportError)

Warning Level:

• When sigan is None while attempting to discover actions (in discover/__init__)
• From the connect() method of the signal analyzer interface when using a mock signal analyzer

Info Level:

• When data loss occurs during IQ streaming and a retry is triggered (in acquire_time_domain_samples)

Bumps patch version to 3.1.5

Suggest changing the overload logging to debug.

Is there a reason this is marked as draft?

Nevermind. I suspect it is because it is waiting on scos-actions PR.
