Restructure docs regarding shipyard file

[christian-kreuzberger-dtx]

As part of keptn/examples#166 I took the chance and restructured our docs regarding Shipyard file.

1. I believe that there was too much information hidden in the Continuous delivery section, hence I have moved it out to the Manage Keptn/Shipyard section.
   
   Preview: https://deploy-preview-815--keptn.netlify.app/docs/0.8.x/manage/shipyard/

2. I have also added an example of adding a remediation sequence to the Update shipyard docs (Preview: https://deploy-preview-815--keptn.netlify.app/docs/0.8.x/manage/shipyard/#add-remove-a-task-sequence-to-from-a-stage scroll down to Use Case 2)

3. Multi-stage continuous-delivery has been extended by multiple examples. Preview: https://deploy-preview-815--keptn.netlify.app/docs/0.8.x/continuous_delivery/multi_stage/

4. A basic example for a remediation sequence was added in Automated Operations / Remediation Config. Preview: https://deploy-preview-815--keptn.netlify.app/docs/0.8.x/automated_operations/remediation/
   

5. Update project instructions have been slightly adapted. Preview: https://deploy-preview-815--keptn.netlify.app/docs/0.8.x/manage/project/#update-a-project

I like it that you moved this section to this page.

[christian-kreuzberger-dtx]

We still need to make sure we update this section regularly. It gets outdated so quickly...
