Title: Add timeout for fetch file

Currently, when fetch a file, the connection's connect timeout
and read timeout is based on the default jvm setting, in this change, I change it to
use spark.worker.timeout. This can be usefull, when the
connection status between worker is not perfect. And prevent
prematurely remove task set.
