geo-rep: Fix the name of changelog archive file

Background:
The processed changelogs are archived each month in a single tar file.
The default format is "archive_YYYYMM.tar" which is specified as "%%Y%%m"
in configuration file.

Problem:
The created changelog archive file didn't have corresponding year
and month. It created as "archive_%Y%m.tar" on python2 only systems.

Cause and Fix:
Geo-rep expects "%Y%m" after the ConfigParser reads it from config file.
Since it was "%%Y%%m" in config file, geo-rep used to get correct value
"%Y%m" in python3 and "%%Y%%m" in python2 which is incorrect.
The fix can be to use "%Y%m" in config file but that fails in python3.
So the fix is to use "RawConfigParser" in geo-rep and use "%Y%m". This
works both in python2 and python3.
