Add possibility to pass empty password for MySQL user

[rompwow]

Please describe the feature you would like to see implemented.

I've installed the cli and tried creating a dump file. As the password defaults to "root" and I cannot pass an empty string to the --password arg, I cloned the repository and tried editing the file cmd/project/project_dump.go.

I replaced the line 30 password, _ := cmd.Flags().GetString("password")

with password = ""

I then built the cli, but using the cli still returns the same error: FATAL Error 1698 (28000): Access denied for user 'root'@'localhost'

I verified that I can indeed connect using mysql -uroot -hlocalhost and that works perfectly.
