The attribute warn_if_longer_than should result in a warning message email instead of an error email

Current situation
When defining the warning_if_longer_than attribute in a job and the job execution has not terminated after reaching the specified time, two emails will be sent to the assigned receipient. One Email will be sent when the specified time is reached. One Mail will be sent when the tasks ends.

The first email contains one line

2015-07-31 08:07:30.323Z JobScheduler -id=scheduler_id  host=host_namel  port=4444

The subject of the email is [error] Error occurred in JobScheduler operation

When the job terminates a second email is sent. This email contains the task log and is the standard email that will be sent when the mail_on_warning option has the value "yes".

The body of the email contains

2015-07-31 08:08:24.681Z JobScheduler -id=scheduler_id  host=host_name port=4444

Task job1 with ID 283113 () terminated with warnings.

SCHEDULER-712  Task runs longer than the expected duration of 00:00:05

Desired behaviour
When defining the warning_if_longer_than attribute in a job and the job execution has not terminated after reaching the specified time, two emails will be sent to the assigned receipient. One Email will be sent when the specified time is reached. One Mail will be sent when the tasks ends.

The first email contains

Task job1 with ID 283113 () terminated with warnings.

SCHEDULER-712  Task runs longer than the expected duration of 00:00:05

The subject of the email is [warning] Task job1 runs longer than expected duration of 00:00:05

When the job terminates a second email is sent. This email contains the task log and is the standard email that will be sent when the mail_on_warning option has the value "yes".
