Go-ipfs: `ipfs pin` hangs, has no option for timeout

[sneak]

Version information:

ipfs@ipfs:~ $ ipfs version --all
go-ipfs version: 0.4.5-dev-56058c1
Repo version: 4
System version: arm/linux
Golang version: go1.7.4

Type: Bug

Priority: P3

Description:

I have a machine running the ipfs daemon 24/7 that grabs a text file from my ipns namespace, and iterates over the lines, doing an ipfs pin add $ENTRY via cron, to automatically mirror whatever I toss into that file.

I logged in and found a zillion ipfs pin processes sitting there hanging, some days old.

Is it possible to add a timeout for things like ipfs pin (and other things that tend to hang for extremely long periods/indefinitely, like ipfs name resolve)? This would make scripting a lot easier, I could just add a --timeout=60s or something.

This may be related/dupe of #3533.

I think the reason for the hang has been fixed in a recent PR, but for the timeout, you can pass --timeout to any ipfs command (i know, this is pretty much undocumented).
