fluid [WIP]using cache worker set to take on the statefulset

Ⅰ. Describe what this PR does

1.在alluxio runtime type中增加workerType字段，用来指示worker类型（STS,ASTS,DaemonSet） 2.增加cacheworkerset 定义以及相关属性的GET/SET操作（pkg/types/cacheworkerset/interface.go） 3.引入了openkruise依赖后，根据它的特性，只需要手动对work pod的label进行patch SpecifiedDeleteKey = "apps.kruise.io/specified-delete"，且这些worker pod被openkruise advanced statefulset接管，那么就可以做到指定该pod下线了。
