[Build] Use Spring Boot and Spring Cloud BOM to manage versions

[onobc]

In our stream-applications-build/pom.xml we have explicit versions for many libs that are either in the Spring Cloud or Spring Boot BOM.

Improve the build by removing these hardcoded versions.

We should add a comment in stream-applications-build/pom.xml that includes a link to the list of version properties that Spring Boot supports. This will allow users to quickly choose the correct version to override if needed.
