Request: Allow MySQL password to be specified interactively

[Nevario]

Firstly, thank-you for an awesome tool!

For the ultra paranoid of us, who prefer not to leave the MySQL password in an env file (even on a well secured Bastion host), it would be awesome if we could omit the password and specify it interactively with something like a -p flag.

This is how we use currently use Skeema.io which allows this for this workflow.

Please close this request if it's not feasible, but just thought I would mention it... just in case :)

I think this is a good idea (we should support it for all database drivers, not just MySQL). Open to a PR.
