Support Hanami 2.1, improve GVL metrics, and more

Added

• Track error response status for web requests. When an unhandled exception reaches the AppSignal EventHandler instrumentation, report the response status as 500 for the response_status tag on the transaction and on the response_status metric.

Changed

• Require the AppSignal gem in the Grape integration file. Previously require "appsignal" had to be called before require "appsignal/integrations/grape". This require "appsignal" is no longer required.
• Report Global VM Lock metrics per process. In addition to the existing hostname tag, add process_name and process_id tags to the gvl_global_timer and gvl_waiting_threads metrics emitted by the GVL probe, allowing these metrics to be tracked in a per-process basis.

Deprecated

• Deprecate Appsignal::Grape::Middleware constant in favor of Appsignal::Rack::GrapeMiddleware constant.

  To fix this deprecation warning, update the usage of Appsignal::Grape::Middleware like this:

  Ruby

  # Grape only apps
  insert_before Grape::Middleware::Error, Appsignal::Rack::GrapeMiddleware
  # or
  use Appsignal::Rack::GrapeMiddleware
   
  # Grape on Rails app
  use Appsignal::Rack::GrapeMiddleware

• Deprecate the Appsignal.start_logger method. Remove this method call from apps if it is present. Calling Appsignal.start will now initialize the logger.

Fixed

• Fix an issue with invalid request methods raising an error in the GenericInstrumentation middleware when using a request class that throws an error when calling the request_method method, like ActionDispatch::Request.
• Support Grape apps that are nested in other apps like Sinatra and Rails, that also include AppSignal middleware for instrumentation.
• Support Hanami version 2.1. On older versions of our Ruby gem it would error on an unknown keyword argument "sessions_enabled".
• Fix issue with AppSignal getting stuck in a boot loop when loading the Hanami integration with: require "appsignal/integrations/hanami" This could happen in nested applications, like a Hanami app in a Rails app. It will now use the first config AppSignal starts with.
