Adds support for creating state machines for attributes on ActiveRecord

Simple testing of Sidekiq jobs via a collection of matchers and helpers

We have deprecated the legacy Oso open source library. We have plans for the next open source release and we're looking forward to getting feedback from the community leading up to that point (please reach out to us in the Slack #help channel). In the meantime, if you're happy using the Oso open source library now, nothing needs to change – i.e., we are not end-of-lifing (EOL) the library and we'll continue to provide support and critical bug fixes. More context: [here](https://www.osohq.com/docs/oss/getting-started/deprecation.html).

Request log analyzer's purpose is to find out how your web application is being used, how it performs and to focus your optimization efforts. This tool will parse all requests in the application's log file and aggregate the information. Once it is finished parsing the log file(s), it will show the requests that take op most server time using various metrics. It can also insert all parsed request information into a database so you can roll your own analysis. It supports Rails-, Merb- and Rack-based applications logs, Apache and Amazon S3 access logs and MySQL slow query logs out of the box, but file formats of other applications can easily be supported by supplying an easy to write log file format definition.
