snap_scheduler: python3 compatibility and new test case

Problem:
"snap_scheduler.py init" command failing with the below traceback:

[root@dhcp43-104 ~]# snap_scheduler.py init
Traceback (most recent call last):
  File "/usr/sbin/snap_scheduler.py", line 941, in <module>
    sys.exit(main(sys.argv[1:]))
  File "/usr/sbin/snap_scheduler.py", line 851, in main
    initLogger()
  File "/usr/sbin/snap_scheduler.py", line 153, in initLogger
    logfile = os.path.join(process.stdout.read()[:-1], SCRIPT_NAME + ".log")
  File "/usr/lib64/python3.6/posixpath.py", line 94, in join
    genericpath._check_arg_types('join', a, *p)
  File "/usr/lib64/python3.6/genericpath.py", line 151, in _check_arg_types
    raise TypeError("Can't mix strings and bytes in path components") from None
TypeError: Can't mix strings and bytes in path components

Solution:

Added the 'universal_newlines' flag to Popen to support backward compatibility.

Added a basic test for snapshot scheduler.
