Add configuration option for handle_errors to be a noop

[kisp]

This would be useful for development.

Allowing the macro handle_errors at compile time to be defined (configured to essentially act) like

  defmacro handle_errors(metadata \\ quote(do: %{}), do: block) do
    quote do
      unquote(block)
    end
  end

instead of

defmacro handle_errors(metadata \\ quote(do: %{}), do: block) do
    quote do
      try do
        unquote(block)
      rescue
        e ->
          Bugsnex.notify(e, System.stacktrace, unquote(metadata))
          raise e
      end
    end
  end

thus avoiding to wrap the body with a try/rescue, leads to stacktraces pointing to the real location of the exception.

I'm not sure what's the best way to pass this configuration option. Possibly, it can be passed as an option in the

require Bugsnex

statement.

I suppose that the value of Mix.env can be used at compile time, but I'm not sure.
