Fabric8 version misalignment

[TYsewyn]

This project adds version 5.12.2 of the Fabric8 K8s client while it also pulls in version 5.10.2 for the other Fabric8 libraries via spring-cloud-deployer-parent:2.8.0-RC1 -> spring-cloud-dataflow-build:2.10.0-RC1 -> spring-cloud-dataflow-build-dependencies:2.10.0-RC1 -> spring-cloud-dependencies:2021.0.3 -> spring-cloud-kubernetes-dependencies:2.1.3 -> kubernetes-client-bom:5.10.2.

Added this dependency to a Spring Boot application with version 3.0.0.RC1.

Thanks for the report @TYsewyn . We will get this adjusted to use the proper single version.

As for the 2.10.0-RC1 artifacts.. you will notice there is no dataflow server or skipper available. The RC1 is not intended for consumption yet and we only put the deployers out there as spring-cloud-task needed an RC version of deployer (for the spring-cloud release train to proceed w/ RC). The estimated date for the actual RC is 11/14.

Sorry for the confusion. In the meantime, we will get the Fabric dependencies adjusted.

Thanks.

NOTES:

• It was changed 030048c to support startup probes. Hopefully this is easy to override via dependencyManagement for the fabric8 deps in https://mvnrepository.com/artifact/org.springframework.cloud/spring-cloud-kubernetes-dependencies/2.1.5
