Michele Baldessari db2d6f7198 Use on-marked-down shutdown-sessions for redis haproxy conf 
The problem we have with redis can be described as follows:
- Connection is made to redis via haproxy, where haproxy directs to one redis node
- That chosen redis node fails and a new redis node gets promoted
- HAProxy will send *new* connections to redis to the newly promoted
  redis server, but you still have a session active (ie. that has not hit
  timeout), so haproxy will attempt to use that connection.

By using 'on-marked-down shutdown-sessions' we make sure we close
old existing sessions when the redis master node changes.

NB: Cherry-pick not 100% clean due to some context differences

Closes-Bug: #1742086
