Improve librato.com backend stability and add additional error metric reporting
This is the same drop as the previous release. Just marking this as stable.
- Incorrect bucket type specified when creating Gauge buckets
- Additional error checking added when posting metrics to Librato.com
- Log the exception type as a metric if the POST to librato.com fails
