Enable more Sentry integrations (#897)

### Enable
[ExtraErrorData](https://docs.sentry.io/platforms/javascript/guides/react/configuration/integrations/extraerrordata/)
integration in Sentry.

This integration serialized extra data attached to the error event. It
is useful to attach additional context to the error event, as currently
the objects are not serialized and are visible as `[Object]` in the
Sentry dashboard.

### Enable
[HttpClient](https://docs.sentry.io/platforms/javascript/guides/react/configuration/integrations/httpclient/)
integration in Sentry.

This integration will capture failed requests and responses in Sentry.
