Functional Test script results in an authentication error

[Sara Nierodzik]

The script is the "configure_for_func_testing.sh" located in /opt/stack/neutron/tools folder.
When the guidelines are followed from the following link:https://docs.openstack.org/neutron/ocata/devref/development.environment.html the test script displays the following error:

ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)

Possibly due to the version of MySQL version being used:
"Since version 5.7, MySQL is secure-by-default: a random root password is generated upon installation; you need to read this password from the server log. you have to change this password the first time you connect. you cannot use a blank password because of the validate_password plugin."

The fix for this is to include the already set password in order to access the MySQL database.

There might be a better way of fixing the bug rather than copying and pasting in the password on a different line however this fix gets rid of the error.
