Review Comment:
The `SubtaskExecutionAttemptDetailsInfo#host` should rename, right?
Also, the `SubtaskExecutionAttemptDetailsInfo#FIELD_NAME_HOST` and the
front-end should be renamed as well. However, I'm not sure whether the rest
api is called by flink users. If yes, the change is incompatible. Should we
adding an extra field to store the locationString?
Anyway, using the `host` to store `locationString` for rest api does't make
sense.
