After a user fits a pipeline, without `getModel(estimator)`, he needs to go
through each transformer in the pipeline model to find it. The example pipeline
doesn't mean to cover everything in this PR. But this method is very useful:
~~~
val lrModel = pipelineModel.getModel(lr)
~~~
Is this operation useful? I would say yes. If we both agree, the question
becomes whether the current form is okay and what other options we have. I
understand that your concern but we need to expose something that can make a
"working" pipeline in order to ask users to try. We can test this internally
for months, but without users' feedback the use cases we know would be quite
limited. The users should be aware of the fact that this is alpha and we should
not be afraid of changing APIs that make things better.
