New Version 2.2.12 Available

[boriwo]

Provides a number of small fixes and feature enhancements, mainly for CNS. Excerpt from the release notes:

- added support for Cassandra 1.1.X (note there are now different schema
  files for Cassandra 1.0.X and 1.1.X)
- centralized monitoring and management of cns workers through cns
  endpoint and admin UI 
- http default timeout of 5 sec for slow endpoints (can be adjusted
  in cmb.properties)
- bug fix: allow publishing of blank messages
- cns worker to temporarily suspend slow or failing endpoints if more
  than n bad responses are encountered in a rolling window of 60 seconds  
  (threshold can be adjusted in cmb.properties)
- offer configurable white list of acceptable http return codes
  (such as 404 if desired)
- simple login and session management for admin ui to distinguish
  admin and normal users. Note: Currently the only admin user is
  the one configured as cmb.cns.user in cmb.properties, typically
  "cns_internal". Access the admin UI from now on using this link:
