Add Index Templating for ES

[toddroper]

Currently we are building static indexes for ElasticSearch. We should leverage the index templates to create reusable pieces that can be compiled for the different indexes.

This is pretty cool--wasn't aware you could compose index mappings out of components. It will make sense for model_configurations which effectively inherit the model mapping. I suspect we won't add more than a small handful of indices in the future, but let's leave this in the backlog and the next time we create an index--e.g. for extraction jobs(?) --we can try to knock it out simultaneously.
