Subject: [PATCH] Ktest: Added email support

Ktest script will send emails when:
    1: the script is started
    2: the script is cancelled by Ctrl-C
    3: the script failed with fatal errors
    4: the script completes all testing

Users have to setup the mailer provided in config prior to using this script.

Supported mailers: mail, mailx, sendmail
