[opsview-users] Centralized mail notification on the master server

[Kang]

Hello.

Email notification of Opsview distributed monitoring sturcture is occurring
in each slave.
but Mail configuration for every slaves are chore and I had the problem that
slave didn't send notify mail for passive check.

So I tried to modify all mail notification to be done on the master server.
After I knowing that all notify by atom is done by master, I added the
following code at the bottom of /usr/local/bin/atom-generator file.
It works well as i expected.

Note: You must enable both "Notify by Email" and "Notify by WebFeed".
          Delete or disable mail agent on every slave not to receive
duplicated mail.

Thank you.
