Create cron container for Solr delta imports

### Create cron container for Solr delta imports
## Description:

Solr does not contain its own scheduler for doing delta imports of the cores. We will create a long-running sidecar container that calls the Solr web service that starts a delta import. Ideally this container must be set up to not start a new import while one is already running. It should run as frequently as possible to allow for the length of time that the query takes (unknown in production). The web service call is detailed in the Solr documentation, but must be clean=false (do not flush the existing core data) and delta=true (only import / delete data that has changed since the last run).
