ProbeType can't be set programmatically as it is not public

[DebajitKumarPhukan]

Issue:
The enum org.springframework.cloud.deployer.spi.kubernetes.ProbeType is not "public" making it inaccessible when attempting to perform org.springframework.cloud.deployer.spi.kubernetes.KubernetesDeployerProperties.setProbeType()

Example:

        KubernetesDeployerProperties kubernetesDeployerProperties = new KubernetesDeployerProperties();
        kubernetesDeployerProperties.setProbeType(<This is what is not allowed due to visibility issue>);
