Update version-related info and publish on PyPi

[scaleoutsean]

12.3.1 can't be installed from the network because it hasn't been published.

Furthermore, when latest v12.3.1 is deployed with setup.py install, I see this:

...
Using /usr/local/lib/python3.10/dist-packages/enum34-1.1.10-py3.10.egg
Finished processing dependencies for solidfire-sdk-python==12.3.0.0

Indeed, a whole bunch of files hasn't been updated, for example setup.cfg:

$ cat setup.cfg | grep "12.3"
current_version = 12.3.0.0

These problems make it hard to see what's installed, as pip consequently gives wrong version information. After installing "12.3.1" with python3 setup.py install:

$ python3 -m pip list | grep sdk
solidfire-sdk-python 12.3.0.0
