Rename heartbeats to cron check-ins and other improvements

Changed

• Remove the HTTP gem's exception handling. Errors from the HTTP gem will no longer always be reported. The error will be reported only when an HTTP request is made in an instrumented context. This gives applications the opportunity to add their own custom exception handling.

  Ruby

  begin
    HTTP.get("https://appsignal.com/error")
  rescue => error
    # Either handle the error or report it to AppSignal
  end

• Rename heartbeats to cron check-ins. Calls to Appsignal.heartbeat and Appsignal::Heartbeat should be replaced with calls to Appsignal::CheckIn.cron and Appsignal::CheckIn::Cron, for example:

  Ruby

  # Before
  Appsignal.heartbeat("do_something") do
    do_something
  end
   
  # After
  Appsignal::CheckIn.cron("do_something") do
    do_something
  end

Deprecated

• Calls to Appsignal.heartbeat and Appsignal::Heartbeat will emit a deprecation warning.
