Ceilometer is bombing logs with connection retries when redis is down

[Sagi (Sergey) Shnaidman]

When redis is down, the ceilometer tries to reconnect and dumps this to logs a few times in a second. This makes its logs huge size and overload our logs servers.

there already exists configurable retry logic: https://github.com/openstack/ceilometer/commit/3459bc59f2014afd98865f8dfd93a0197424d518

we're switching to tooz partitioning and that also has configurable retry logic (according to jd). will close if this works (or you can reraise if broken)

[gordon chung (chungg)]

we use tooz now completely for coordination[1]. please use those options and target tooz if it don't work for you.
