Add parent/child pipeline limitations
What does this MR do?
Related issue: #16094 (closed)
With the introduction of parent/child pipelines we need to add some limitations to prevent abuses:
- A child pipeline cannot create further child pipelines
- When defining a child pipeline
trigger:include
cannot contain more than 3 entries
What are parent/child pipelines? A pipeline (parent) can create a downstream pipeline (child) within the same project in order to breakdown a pipeline into composable primitives.
