SOLR - add tests using Docker image

[jnioche]

Similar to what we have for ES, the tests could spin a Docker container for SOLR and check that documents are indexed as it should be.

@mvolikas since you use this module, any chance you would be able to have a look at this one? Or any of the other issues for SOLR?

[mvolikas]

Sure, thx! I was actually having a look earlier today :)

Hi there!
I have opened a PR to branch 851. I fixed the StatusBoltTest and added a very simple IndexerBoltTest (just checks if the tuple is acked). Note that I used a slightly different approach: Now the solr/cores/ configuration files are used for the tests, and the cores are created explicitly. For the Indexer, I could also add a query to Solr that checks that the document is actually in the core. What do you think?
