Support BuildProperties bean in Spring Boot by writing META-INF/build-info.properties

[plaird]

The BuildProperties bean in Spring Boot is loaded from data populated in META-INF/build-info.properties

• https://docs.spring.io/spring-boot/docs/current/maven-plugin/reference/htmlsingle/#goals-build-info
• https://golb.hplar.ch/2019/06/expose-build-information.html#spring-boot
• https://www.vojtechruzicka.com/spring-boot-version/
• https://docs.spring.io/spring-boot/docs/current/api/org/springframework/boot/info/BuildProperties.html

It allows for custom properties to be added. We should support that too.
