[jjbb] for scheduling e2e jobs

[v1v]

What

Create the JJBB definition (aka the Jenkins UI jobs) for:

• The scheduling twice a day as requested
• The e2e pipeline.

Create the e2e pipeline skeleton, the implementation for what to run to be done in a follow up.

Why

It was requested to create a scheduled execution of the new E2E twice a day and notify in slack the outcome.

Further details

I decided to enable a Multibranch Pipeline to be able to test the pipeline manually if needed on a PR basis. It will only be triggered automatically on a daily basis (twice).

In my experience, Multibranch Pipelines help to iterate faster since we can work on a PR basis.

Notifies

#417 and #393

[v1v]

Quite basic pipeline to only checkout the source code and notify the status in slack/email.

TBC in a follow up
