[SPARK-3139] Made ContextCleaner to not block on shuffles
As a workaround for SPARK-3015, the ContextCleaner was made "blocking",
that is, it cleaned items one-by-one. But shuffles can take a long time to be
deleted. Given that the RC for 1.1 is imminent, this PR makes a narrow change
in the context cleaner - not wait for shuffle cleanups to complete. Also it
changes the error messages on failure to delete to be milder warnings, as
exceptions in the delete code path for one item does not really stop the actual
functioning of the system.
