Description

UpdateProcessorChains must currently be defined with XML in solrconfig.xml. We should explore a scriptable chain implementation with a DSL that allows for full flexibility. The first step would be to make UpdateChain implementations pluggable in solrconfig.xml, for backward compat support.

Benefits and possibilities with a Scriptable UpdateChain:

• A compact DSL for defining Processors and Chains (Workflows would be a better, less limited term here)
• Keeping update processor config separate from solrconfig.xml gives better separations of roles
• Use this as an opportunity to natively support scripting language Processors (ideas from SOLR-1725)

This issue is spun off from SOLR-2823.
