Wipe Solr Stats

[abelpink]

Wipe the Solr stats before hard launch, since these stats include pages we visited and developed against during development.

Launch date tbd, but we will want to do this right before.

curl -X POST -H 'Content-type:application/json' -d '{"delete":{"query":"*:*"}}' "http://localhost:8983/solr/statistics/update?commit=true"

The above command irreversibly wipes all Solr stats.
