ZEPPELIN-1773. Remove method destroy() in Interpreter
### What is this PR for?
IMHO `destroy` is a little functional duplicated with `close`. And it seems
currently only cassandra use destroy and it just calls `close()`
https://github.com/apache/zeppelin/blob/master/cassandra/src/main/java/org/apache/zeppelin/cassandra/CassandraInterpreter.java#L231.
So IMO, we could delete destroy method, also we can delete the destroy method
in `InterpreterGroup`. Besides, I move the terminate remoteInterpreterProcess
in `close`.
