Version 1.2.0 Release

The big change in this release is a change from Thrift to CQL. A lot of work was done to make CQL perform better than the thrift code. Queries are noticeably faster. The release will create new index tables that can be queried via the CQL shell. The code is compatible with data ingested by the previous release of Kairos (1.1.3).

The release is not compatible with schema created by 1.2 beta 1 and beta 2.

Now for all the heaps of coolness that can be found within this release

Uses CQL for reads and writes
Up to 8x improvement in query speed - wait what?? Yes you read that right, I hit the turbo button.
New service api for storing whatever you want in Kairos. (metadata, configuration, etc..)
Extra metrics for tracking queries - even logged if the query fails
Added ability to specify node roles (ie ingest or query node)
Requires C* 2.1 or higher.
Added a demo module that lets you load up a year of demo data to play with

Fixes
