Description

Problem:
Today the user needs to make sure that crucial UpdateProcessors like the Log- and Run UpdateProcessors are present when creating a new UpdateRequestProcessorChain. This is error prone, and when introducing a new core UpdateProcessor, like in SOLR-2358, all existing users need to insert the changes into all their pipelines.

A customer made pipeline should not need to care about distributed indexing, logging or anything else, and should be as slim as possible.
