RAG Template Set indexing_key variable from upstream listener

[mirkenstein]

RAG Template set indexing_key

1. Set variable for indexing_key = upstream_listener.outputs everywhere to factor out dependencies across db backends and platforms.

Currently the hard coded _outputs__chunker does not work for different platforms.
In some instances it renders as _outputs.chunker

This is already implemented in the text vector search example

2. Add working set of parameters to chunker model
