Munin plugins to monitor Zimbra metrics reported by zmprov.

• zimbraAggrQuota - monitor Aggregate Quota
• zimbraCount - monitor various object counts e.g. account, alias, dl, etc

Because zmprov takes a few seconds to return answers, we use a cronjob to write values to a file, and plugins read values for the file instantly.

Execute install.sh as root. Then restart munin-node service and wait ~10 minutes for graphs to appear.

Tested with Zimbra 8.0.x and Munin 2.0.x.
