should we instead name these packages by the component they target so its a bit more obvious, so this one would be called drive

I'm a bit wary of creating nested packages, in these cases we have to be sure we're not going to import anything from the parent package,
since the parent will most likely import from this one.

I don't really like that this ends up in actions but I do think it makes sense it is an action being taken. I intend to have Wipe action for storage controllers too so we can use it to delete raid configs and nvme namespaces.
