Introduce Rails common error reporter

[skatkov]

fixes #2

Most error monitoring software claim support for Rails.error.handle, but no support for Rails.error.recordapproach. But .handle method swallows errors and that makes it's usage complicated in our case.

In this PR I suggest usage of Rails.error.report, this method is used underneath of Rails.error.handle, so should be as well supported by most error monitoring services and it fits perfectly to our use case.

If we merge thos feature, this gem will be feature complete for usage in Cheddar's monolith application.
