geo-rep: Config file upgrade

2014-02-11T01:07:42+00:00

When old config file is used with new geo-rep, config item like
'georep_session_working_dir' was missing in old config file.

With this patch geo-rep sets the default value for new items.

Following config options supported:
  - georep_session_working_dir
  - gluster_params
  - ssh_command_tar

geo-rep: get new config value after config value reset

2014-02-03T04:26:40+00:00

When config.read is called it preserves the previous values
from the the previously opened config file.

For example
import ConfigParser
config = ConfigParser.RawConfigParser()
config.read("defaults.conf")
config.read("preferences.conf")

When change in config file is identified it will open new
instance of config to avoid getting old config values.
