Comment:

 (In [149c4d4f6e256deb1ed145cf22849e2bd03ab5b7]) Implement a consistent
 retry policy in the random/client/hash director:

 If the first (policy-chosen) backend fails to get us a connection,
 retry a random backend (still according to their weight) until
 retries are exhausted.

 Kristian sent a proof of concept patch, I just cleaned it up and made
 it compile.

 Thanks to:      Kristian
