**BUG REPORT**
***Description***
"bookkeeper listbookies -a" crashes on unresolvable DNS names for a bookie,
instead of going on to print other bookies.

***To Reproduce***
Steps to reproduce the behavior:
1. Remove one hostname-identified bookie's DNS A record
2. Wait for DNS cache to expire, or flush
3. Issue the command: ./bookkeeper listbookies -a
***Expected behavior***
I expected to see the bookie hostname without any IP address (or a more
meaningful warning) but anyway it should go on to printing the other bookies'
instead of crashing.
