Subject: [PATCH] Add opt-in build scan integration with Gradle Enterprise

This commit adds opt-in build scan integration with Gradle Enterprise.
When the GRADLE_ENTERPRISE_URL environment variable is set on a
developer's machine or on CI, a build scan will be automatically
uploaded to Gradle Enterprise at the end of the build.

This initial integration will establish a baseline for Spring
Framework builds. Once that baseline has been established we can use
the build scans to identify ways in which the build can be optimized
and updated to make use of Gradle's build caching which should reduce
build times, significantly so for changes that only affect tasks near
the leaf nodes of the task graph.
