   Hi @sebastian-nagel,
   
   I changed the use of `ObjectCache.class` to an internal CACHE object, to avoid changing the behavior of other functionalities. In this case it is not necessary to have a different instance of `IndexWriters.class` for each `Configuration.class`. This is beacuse the index writer's configuration is handled in other individual file.
   
   Also, I fixed an issue in `TestElasticIndexWriter.class` (associated with the use of `IndexWriterParams.class`), which causes the unit test fail.

> SolrUtils should return an array of SolrServers and read the SolrUrl as a comma delimited list of URL's using Configuration.getString(). SolrWriter should be able to handle this list of SolrServers.
> This is useful if you want to send documents to multiple servers if no replication is available or if you want to send documents to multiple NOCs.
> edit:
> This does not replace NUTCH-1377 but complements it. With NUTCH-1377 this issue allows you to index to multiple SolrCloud clusters at the same time.
