geo-rep: Handle Config parser errors

Python ConfigParser lib has two methods, readfp and read, it should
be used as follows.

    readfp(open("defaults.conf"))
    read("custom.conf")

ConfigParser.read(path) ignores any file errors, which is intentional
since errors are handled while loading default config.

Geo-rep uses only one config file(Session config in Master side and
Template config on Slave side) so we should use readfp to avoid
skipping OS errors.

config.read is retained in case of `--config-set-rx` where glusterd
creates new template config file.
