Python2->Python3 update, Python2 unsafe

[qinzhang22]

For python-pam, this is already built with xs8 and xs9. The XS8 package is in rt-next now.

xsconsole xenrt test passed: 3864890

Do not forget to tag before this merge, with major version bump up (for in-compatibility)

Why've you used Lang() here and elsewhere in the commit? I think it is not normally used with dynamic values. Normally it is only used with static labels like Operation, Storage Repository, etc.

[qinzhang22]

I used Lang() as I'm not sure the object is a string or a bytes object. Let's remove encode here to see how it goes.

Please apply change request that I originally made in PR 18 to keep Python3 working:
#18 (comment)

Here is Pau's hard disagree comment again:
#15 (comment)
Andrew's initiative to keep Python2
#15 (comment)
and also Alex questioned splitting the code base of packages recently when there is no need to do so.

This change is small and even reduces the amount of changed lines:

try:
    import xmlrpclib
    import SocketServer
    import SimpleXMLRPCServer
except:
    import xmlrpc.client as xmlrpclib
    import socketserver as SocketServer
    import xmlrpc.server as SimpleXMLRPCServer

In addition, there are xsconsole plugins on xs8. You can find one with rpm -qa on xs8

rpm -qa | grep xsconsole

What about xsconsole plugins by partners?
Can we check them?

Until these are checked and updated as well, we cannot declare xsconsole update work as finished.

We has a new agreement here: #18 (comment). That is move for Py3.6 baseline as there's no dependency of xsconsole that's going to need it to stay py2 compatible. And my PR is working on XS8. So what's your point we have to make such change here?

I don't know what partners use our xsconsole and how to check that. @rosslagerwall and @andyhhp Can you provide any information here?

Merged in split form with #24, #25, #28 and the change force the use of Python3 is no longer needed.
