"""Integration test for the ssh module.

This module has two tests to verify if we can create ssh keys
through the ``ssh`` module. The first test asserts that some keys
were not created while the second one verifies if the expected
keys were created.

(This is ported from
``tests/cloud_tests/testcases/modules/ssh_keys_generate.yaml``.)"""
