AutoReconnect exception while replica sets vote for PRIMARY

[Yurii Prokulevych]

If ceilometer call (ceilometer statistics -m ...) is done while replicas members are voting for new PRIMARY
next traceback might appears in api.og:

2015-04-24 19:08:54.049 13792 ERROR wsme.api [-] Server-side error: "No replica set primary available for query with ReadPreference PRIMARY". Detail:

AutoReconnect: No replica set primary available for query with ReadPreference PRIMARY

IMHO, this has to be handled gracefully.

Thanks,Yurii

ceilometer doesn't do storage no more.
