Subprocess "run" being used on Python2.7

[becurrie]

When attempting to use the create_database_dump utility on a legacy python2.7 system, the subprocess command fails because run doesn't exist in the subprocess module bundled with Python 2.7.

https://docs.python.org/3.5/library/subprocess.html#older-high-level-api

I believe the equivalent is call instead of run.

Relevant traceback:

Traceback (most recent call last):
  File "/Users/brett/.virtualenvs/iris/bin/pganonymize", line 8, in <module>
    sys.exit(main())
  File "/Users/brett/.virtualenvs/iris/lib/python2.7/site-packages/pganonymizer/__main__.py", line 12, in main
    main(args)
  File "/Users/brett/.virtualenvs/iris/lib/python2.7/site-packages/pganonymizer/cli.py", line 89, in main
    create_database_dump(args.dump_file, pg_args)
  File "/Users/brett/.virtualenvs/iris/lib/python2.7/site-packages/pganonymizer/utils.py", line 274, in create_database_dump
    subprocess.run(cmd, shell=True)
AttributeError: 'module' object has no attribute 'run'

Yes, call should be available for Python 2.7. I will fix this and will release it with the upcoming version 0.7.0. I also added a regression test that will at least verify that subprocess.call will be called by the create_database_dump function.

Thanks for reporting!
