Connect build to ge.spring.io.

This change publishes a build scan to ge.spring.io for every local
build from an authenticated Spring committer and for CI where
appropriate access tokens are available. The build will not fail if
publishing fails.

This change also allows the build to benefit from local and remote
build caching, providing faster builds for all contributors.

Additionally, the project will have access to all features of Gradle
Enterprise such as:

- Dashboards to view all historical build scans, along with performance
   trends over time
- Build failure analytics for enhanced investigation and diagnosis of
   build failures
- Test failure analytics to better understand trends and causes around
   slow, failing, and flaky tests

 The primary goal of the https://projects.spring.io/spring-data[Spring Data] project is to make it easier to build Spring-powered applications that use new data access technologies such as non-relational databases, map-reduce frameworks, and cloud based data services.
