Multi-project pipeline view support

[tis-rpage]

Multi-project pipelines, where one pipeline triggers a pipeline in another project, shows only the current projects pipeline, and fails to address the downstream pipelines.

This feature should also support when multiple downstream pipelines are triggered to show them all, just like the web UI.
