[PATCH v3 3/4] Ktest: use dodie for critical falures

From: Tim Tianyang Chen
Date: Mon Mar 26 2018 - 16:17:45 EST


Users should get emails when the script dies because of a critical failure. Critical
failures are defined as any errors that could abnormally terminate the script.

In order to add email support, this patch converts all die() to dodie() except:
* when '-v' is used as an option to get the version of the script.
* in Sig-Int handeler because it's not a fatal error to cancel the script.
* errors happen during parsing config

Changes since v2:
revert a change for opening and appending the config file
Changes since v1:
revert changes for errors happen during config parsing
