On slow systems, we don't want test steps involving tools like scp or
ssh-keyscan to fail because the server had not come up yet.
Therefore, make sure that the server is ready to accept connections
before moving on to subsequent test steps.
Use CAPTIALIZED names for static data and collect them at the top.
Make a note about for future readers about why a test called
ssh_key_authentication suspiciously does not enable the SSH service :)
This should be a non functional change. The idea is to use the topdoc
dir from 9pm when generating the test report.
