Changes to Database example command needed in Docs with new MySQL versions

[Tom Dack]

In newer DB versions, the existing example:

GRANT ALL PRIVILEGES on iam_test_db.* to 'iam_test'@'%' identified by 'some_super_secure_password';

No longer works. Instead, one must now use:

CREATE USER 'iam_test'@'%' identified by 'some_super_secure_password';
GRANT ALL PRIVILEGES on iam_test_db.* to 'iam_test'@'%';

This renders the current documentation out of date.
