This commit adds support for providing a default ThreadPoolTaskScheduler
with sensible defaults. A new TaskSchedulerBuilder is provided with
defaults from the `spring.task.scheduler.*` namespace and can be used
to create custom instances.

If no custom `TaskScheduler` bean is present, `@EnableScheduling` now
uses the auto-configured task scheduler.

Until the fix for JDK-8209506 [1] is available in Java 11 builds,
SSL connections to services using Google's SSL certificate do not work
due to a lack of trust. This affects both our OAuth2 client samples
which were using https://accounts.google.com as an OpenID Connect
provider.

This commit switches the two samples to use Yahoo in place of Google.
