Create a python library for xcat as a starting point for transition to Python based in xCAT3. There are also plans to switch over to using the SoftLayer Python API (over Perl) xCAT-SoftLayer.spec file will ship lib/python/xcat directory. A new bin file 'softlayer_nas.py" is created to help assist users with mounting and unmount the SoftLayer NAS shared filesystem DevOps Task #10959 unser xCAT_SoftLayer project
