Option to disable backups when moving DBs

[earthday47]

Is your feature request related to a problem? Please describe.
I want to use the cli to copy databases from a multisite with >30 databases. By default database:copy and database:copy:all backup the DBs on the target environment first, which could create a lot of clutter on the server. I've had issue with running out of disk space as well.

Describe the solution you'd like
Add the --no-backup option to database:copy and database:copy:all so you can skip the copy operation.

Describe alternatives you've considered
