<sits forever>

I'm not exactly sure why ipfs pin add -r fails (and I wish it would describe exactly what it's doing when the deadline hits), but I'm opening this issue because I think ipfs refs -r should have the same behavior. I'd rather them both give up after a reasonable period of time, or both hang forever, or both have a --timeout parameter defaulting to the same value.

Already in #1630

All commands respect a --timeout flag, example: ipfs refs -r <hash> --timeout=10m
