Article Component Elastic Integration

[jonwinton]

Is your feature request related to a problem? Please describe.

When #24 is done we will need to integrate the article component with ElasticSearch so we can populate the feed component.

Describe the solution you'd like

We need to handle following questions/tasks:

• Write a search service
  • Do we use an open source query builder or write our own
  • The query builder needs to be universal
  • Must be able to execute a query from the client
  • Must be able to execute a query from the server
• Define a mapping for an index based on the metadata in the feed component requires
• Write a handler for the article component to ship data to the Elastic index

Describe alternatives you've considered

N/A

Additional context

• We will want to refer to the NYMag implementation for building indices and search.
• We'll also want to amend the first-run bootstraps to include a greater set of sample data to demonstrate how the feed works and it's features
