IMPALA-992: Rerun past queries from history in shell

This patch adds a new command "rerun" and a shortcut "@" to impala-shell
. Users can rerun a certain query by its index given by history command.
A valid index is an integer in [1, history_length] or
[-history_length, -1]. Negative values index history in reverse order.
For example, "@1;" or "rerun 1;" reruns the first query shown in history
and "@-1;" reruns the last query. The rerun command itself won't appear
in history. The history index is 1-based and increasing. Old entries
might be truncated when impala-shell starts, and the indexes will be
realigned to 1, so the same index may refer to different commands among
multiple impala-shell instances.

Testing: A test case test_rerun is added to
shell/test_shell_interactive.py
