chore (quickstarts/maven/spring-boot-crd) : Update outdated methods i…

…n Spring Boot CRD (eclipse-jkube#1985)

Spring Boot CRD seems to be broken. It seems to be inheriting
kubernetes-client from jkube but it's using outdated `customResource`
raw api calls.

Update it to use genericKubernetesResource() DSL call instead.
