Fix NetApp AutoSupport Shortcomings.

This patch addresses several problems with the current implementation.

1. Appending a record to EMS should not in itself trigger ASUP
delivery. These should be separately scheduled and Openstack cinder
should have no role in ASUP scheduling or delivery, only a role in
logging via EMS.

2. Log frequency should be adjusted from weekly to hourly.

3. The log message should be useful for support. It should include
release (Havana, Icehouse, Juno, etc.) version (2014.1.1), and
distribution information (RHEL-OSP, etc.) rather than simply noting that
the message came from "Openstack."
