[cbbackup] Why does cbbackup refuse to retrieve design docs from remote nodes?

Hello,

I'm working on implementing backups for my local CB cluster. I've found the code where the node list is filtered and all non-localhost entries are removed.

Is there a reason for this? Ideally, I would prefer to run my backups from a single backup node instead of needing to SSH into one of the CB nodes, but it seems the cbbackup code doesn't agree with me.

Who is wrong here? Me or the code?

Thanks!
