Renaming split-names to split-names-from-streaming
Part of code for https://github.com/huggingface/datasets-server/issues/755
Since we are going to handle two different sources for split-names, the previous worker/processing step/cache-kind have to be changed to /split-names-from-streaming (There already exist /split-names-from-dataset-info)
TODO: Once this PR is merged, a new PR with changes on docker image/chart should be sent in order to change the WORKER_ONLY_JOB_TYPES param as well
