This script was written in python2,
however the python-pexpect module does not exist anymore on Groovy (replaced by python3-pexpect)

A quick and dirty fix is to change the shebang from:
  #!/usr/bin/python2

To:
  #!/usr/bin/env python3

Tested on Groovy s390x LPAR (s2lp4) and the test can be executed.

I think it is not the best way to fix this, as we will need to run this test on older releases too (for Trusty ESM), it's better to test if this will cause any problem on them first.
