Icon for the Minigraph in pipeline list for manual actions

Description

For pipelines with a stage that contains only untriggered manual actions, we show the skipped icon in the pipeline list:

and the play button in the full pipeline graph:

The icons should be the same in both cases.

Proposal

We should show the play button in the simplified pipeline in the pipeline list rather than the skipped icon. I'm not sure if the play button should be clickable though, since it's likely people will click on it to see more details rather than directly triggering the action.

Single Source of Truth

Therefore the following icon is the one we should use whenever the status indicates a manual action is required:

This should btw also count for: https://gitlab.com/gitlab-org/gitlab-ce/issues/22642

extended mockup would be:

Icon can be found here

Tooltip should say:

Production: manual action required

Order in which the statusses and thus icons should be represented (priority list):

failed > warning > pending > running > manual > canceled > created > success > skipped
