Email notification service that notifies System admins on critical events in the application.

Add an email notification service that sent email notification messages to System admins on critical events in the application.

For a small JIRA installations or hosted instances where there are not dedicated webserver administrators and nobody monitor the application, often problems need to become critical before are investigated.

Similary to JRA-15109 there are many advantages of such as feature.

Perhaps the most significant are:

1. Monitor in a better way "helth" of the application - some of the user don't even know what is a web app server (Tomcat/Reisen) and where to look for the log files.
2. Diagnose problems in their early stage - e.g. mailhandler issues/misconfiguration are not visible without access to the log file.
3. Users would attempt to address common and obvious issues listed in the log file if the would have a "convenient" access to the logs.
4. In overall it should impact number of support request logged in SAC.

Many web based application already include similar features.

A simple solution only send the logs or warnings, where complex implementations include ability to set up triggers and monitors on various custom defined events.
