Functional testing script password update
Functional testing script password update

This patch includes a fix for "configure_for_func_testing.sh" script.
When the guidelines are followed from the following link:
https://docs.openstack.org/neutron/latest/contributor/testing/testing.
html
the test script displays the following error:
ERROR 1045 (28000): Access denied for user 'root'@'localhost'
(using password: YES).
The fix for this is to include the saved password in order to access the
MySQL database.
