UX: Inline trigggered jobs in parent pipeline

[jmendiara]

Scenario:

1. The pipeline triggers a build
2. The UI shows a link to the triggered build in the current pipeline
3. The user must click there to go to the new build and see whats going on.
4. GOTO 1 😄

It would be nice to inline the triggered steps into the main pipeline view (recursive) to see what are the real progress, see logs and so on. This way, users will see ALL the steps involved, what is the real progress... and can go directly to steps to get logs, artifacts, without clicking and clicking

I had to inline steps by my self in the main pipeline and not using triggers to make our team happy.
I ended complicating the maintenance of .buildkite files..., just for an UX issue

WDYT? Sounds reasonable?
