Add slack alert when 4.13 rollback job fails

[shellyyang1989]

Per slack thread, we've decided to make a slack alert for the 4.13 rollback failures.

The channel I use here doesn't exist, I'll create it if it looks good to reviewers.

Per the slack channel convention, looks like we need to rename it to alerts-ocp-rollback-ci. WDYT @wking @jianlinliu

If we are reporting both failure and error, it might be worth including {{.Status.State}} here, like:

Job {{.Spec.Job}} ended with {{.Status.State}}, see <{{.Status.URL}}|here>.

or some such. <{{.Status.URL}}|View logs> seems more popular grepping for existing report_template content, and personally there is more in the job-details page in logs, so I like here. But it's not pinging me, so 🤷, feel free to take this feedback and do whatever you want with it, including leaving the string you're currently using in place.

/hold in case you did want to make changes

@shellyyang1989: no rehearsable tests are affected by this change

Interacting with pj-rehearse

Comment: /pj-rehearse to run up to 10 rehearsals
Comment: /pj-rehearse skip to opt-out of rehearsals
Comment: /pj-rehearse {test-name}, with each test separated by a space, to run one or more specific rehearsals
Comment: /pj-rehearse more to run up to 20 rehearsals
Comment: /pj-rehearse max to run up to 35 rehearsals
Comment: /pj-rehearse auto-ack to run up to 10 rehearsals, and add the rehearsals-ack label on success
Comment: /pj-rehearse abort to abort all active rehearsals

Once you are satisfied with the results of the rehearsals, comment: /pj-rehearse ack to unblock merge. When the rehearsals-ack label is present on your PR, merge will no longer be blocked by rehearsals.
If you would like the rehearsals-ack label removed, comment: /pj-rehearse reject to re-block merging.
