[CARBONDATA-3863]after using index service clean the temp data

Why is this PR needed?
each query that use index server will create a folder under
/tmp/indexservertmp. but when query finished the folder will not
be delete. therefore as the number of queries increases, the
folders in /tmp/indexservertmp will increased. then will get
the directory item limit.

What changes were proposed in this PR?
after query finished delete the folder that created.
clean the /tmp/indexservertmp after index server restart.
run a thread that will delete the folder in /tmp/indexservertmp
that has existed for more than 3 hours.

This closes #3855
