Dynamic implementation in doOnError() or onErrorResumeNext for release builds

It will be great to have the ability to add dynamic implementations for logging purposes for `doOnError()` or `onErrorResumeNext`.

eg. imagine that we want to track logs for crash reporting reasons for our data layer, so what we could do, is to create a custom `ErrorLoggingAction` and we could attach it manually. Another option is to create an observable facade which it could include this logging automatically.

But imagine the interface `RxLogObservableAdapter` which can implement our logic there and we must init it once in `Application` class.
