This command supports removing volumes associated with an app. The app in
question must be undeployed before you try to remove volumes. See "abra app
undeploy <domain>" for more.

The command is interactive and will show a multiple select input which allows
you to make a seclection. Use the "?" key to see more help on navigating this
interface.

Passing "--force/-f" will select all volumes for removal. Be careful.
