[Feature Request] Perform DB backup from CLI

[spAnser]

It would be helpful to be able to perform database backups through the command line.

Yes there is probably fairly easy ways to do this already, but having Craft already handling the MySQL user, password, database name, file naming and compression. It would be much easier to just call a quick backup/db action through the CLI.

./craft backup ./backups

# create backup in working directory with custom filename
