Issue: Following tests are failing sporadically on PB2.
    ./mtr mysql_secure_installation --suite=interactive_utilities
    ./mtr mysql_secure_installation_ssl --suite=interactive_utilities

    Test is not passing full command prompt to expect module.
    Issue with regex string search in expect module for
    'Reload privilege tables now? (Press y|Y for Yes, any other key for No) :'

    fix:
    Replaced string search 'Reload' with 'Reload
    privilege tables now?' string and other expect prompt to avoid such failures in future.
    Tested with repeated runs, it's working fine.
