[Al-assad]

In the discussion after #220 , i'm glad that we've come to a consensus on Flink k8s-native mode support for StreamX. The related development task will be consolidated on the feature-k8s branch, the following is the task lists:

• [streamx-plugin/streamx-flink-submit] refactoring the public flink job submit api #247

• [streamx-plugin/streamx-flink-submit] submission/termination process of flink k8s-native session/application mode #248

• [streamx-plugin/streamx-flink-submit] docker image build process in flink application mode #249

• [streamx-console, streamx-plugin] workspace storage compatibility for HDFS and LFS #251

• [streamx-console/streamx-console-server] compatible with both flink yarn/k8s modes task submission/termination #250

• [streamx-console/streamx-console-server] compatible with collection of flink statistics info (such as job overview) in k8s/yarn mode #255

• [streamx-console/streamx-console-webapp] provide additional GUI adaptations for flink k8s mode #252

Welcome to participate in the development of each small task 🙌.
