Replace "email" ZEDLETs with "notify" ZEDLETs
Several ZEDLETs already exist for sending email in reponse to a particular zevent. While email is ubiquitous, alternative methods may be better suited for some configurations. Instead of duplicating the "email" ZEDLETs for every future notification method, it is preferable to abstract the notification method into a function. This has the added benefit of reducing the amount of code duplicated between ZEDLETs, and allowing related bugs to be fixed in a single location. This commit replaces the existing "email" ZEDLETs with corresponding "notify" ZEDLETs. In addition, the ZEDLET code for sending an email message has been moved into the zed_notify_email() function. And this zed_notify_email() has been added to a generic zed_notify() function for sending notifications via all available methods that have been configured. This commit also changes a couple of related zed.rc variables. ZED_EMAIL_INTERVAL_SECS is changed to ZED_NOTIFY_INTERVAL_SECS, and ZED_EMAIL_VERBOSE is changed to ZED_NOTIFY_VERBOSE. Note that ZED_EMAIL remains unchanged as its use is solely for the email notification method. Signed-off-by: Chris Dunlap <cdunlap@llnl.gov>
