The more I use pipelines the more useful they would be come if I could specify a list of pipelines that automatically get run on a type or index level.

This would also save some overhead of specifying what pipeline to use when a huge percentage of use cases that are using pipelines will never change. This would also make the api easier to use.

Some questions would be, if I specify a list of pipelines on an index, what would happen if I specify a pipeline to use, Would it be a merged list or just the specified pipeline to run.
