add auto retry functionality

[lws-llc]

What happened:

I have a service now script that runs to open and close change tickets.

At the beginning of my job, the service now script opens a change.

I cannot automatically kick off the "cancel" job if my pipeline fails which will leave an unattended open change ticket.

What you expected to happen:

If my pipeline fails at any point, I need to kick off the cancel job in order to close out the change ticket it initiated.

How to reproduce it:

Create a repository on Github and use it to create a pipeline in Screwdriver.cd.

This is how it should work:
Create 2 jobs.
If job one fails, have job two start.
If job one is successful, job two does not run.
