Add --host and --port parameters

[Ricardocanul7]

Could it be possible to add --host and --port options to the command?

I have a case where I have a separate docker container for a database so I have to communicate my node container to my DB container, so after installing in my node container the dbdump package and also mysql-client to satisfy mysqldump command requirement in dbdump , I'm able to connect with my DB container using raw mysqldump, but when trying to use dbdump it doesn't work as it needs the host and port values to connect to a remote database and apparently those options are not available.

cmd += `-u ${user} ${password ? '-p' + (password === true ? '' : password) : ''} ${db}`;
