Joe McDonnell aa4050b4d9 IMPALA-11976: Fix use of deprecated functions/fields removed in Python 3

Python 3 moved several things around or removed deprecated
functions / fields:
 - sys.maxint was removed, but sys.maxsize provides similar functionality
 - long was removed, but int provides the same range
 - file() was removed, but open() already provided the same functionality
 - Exception.message was removed, but str(exception) is equivalent
 - Some encodings (like hex) were moved to codecs.encode()
 - string.letters -> string.ascii_letters
 - string.lowercase -> string.ascii_lowercase
 - string.strip was removed

This fixes all of those locations. Python 3 also has slightly different
rounding behavior from round(), so this changes round() to use future's
builtins.round() to get the Python 3 behavior.

This fixes the following pylint warnings:
 - file-builtin
- long-builtin
- invalid-str-codec
- round-builtin
- deprecated-string-function
- sys-max-int
- exception-message-attribute

Testing:
 - Ran cores tests

What is impala-gdb.py?

This is a collection of Python GDB functions (macros) that can be invoked from a GDB session to aid analysis of Impala core dumps.

To use the functions, source impala-gdb.py as follows:


(gdb) source $IMPALA_HOME/lib/python/impala_py_lib/gdb/impala-gdb.py

Currently, the following functions are available:

1. find-query-ids
2. find-fragment-instances

Here's a sample interaction:

(gdb) help find-query-ids
Find IDs of all queries this impalad is currently executing.
(gdb) find-query-ids

(gdb)
(gdb)
(gdb) help find-fragment-instances
Find all query fragment instance to thread Id mappings in this impalad.
(gdb) find-fragment-instances
