run-unit-tests on ykush devices

I say lets call it acroname (lower case) and not device as we call our cameras devices

[maloel]

In general:

• It seems both acroname and ykush are really implementations of some common 'hub' interface, except there isn't a common interface defined
  • Otherwise I don't see why we're going the object-oriented route: the modules themselves are objects, too
  • We're not envisioning a use-case where more than one acroname, or any combination of hubs exists, right?
• The relay is just a forwarder - I'm not sure I see the need for the relay to duplicate all the functions of the actual hub implementation
  • E.g., disable_ports(): once you have an instance of a hub, why not call this function directly on it?

I think the direction is good, but maybe the 'relay' (I like 'hub' better) is your interface that acroname and ykush implement? You still need a create() function, but that's about it. Once you have a hub instance (that's your has_relay), you just need to use it...

This is not valid, I get:

TypeError: catching classes that do not inherit from BaseException is not allowed

It should be:

except BaseException:

Same in line 176.

Remove the ()

I think this is now less relevant now that there're alternatives - let's turn this into a log.d

[maloel]

And same in ykush

[maloel]

And make it lower-case and remove the ! :)

[AviaAv]

sure, I'll do the same on ykush.py (log.w -> log.d)

@Nir-Az this needs to be coordinated with changes to libCI, so I'm not merging yet
