Description

Currently the SolrWriter presumes a single collection to be written to.  The new collection strategy for Solr implies a collection per sensor.  Also, there are a few rough edges in the writer which could stand smoothing:

• By default, we use solr's implicit commit mechanism, rather than committing at the batch granularity.  This may result in lost data on worker failure.
• We do not use the the batch add api, but rather message-by-message add
