    glusterd: Fix gsyncd upgrade issue

    Backport of http://review.gluster.org/14898/

    Problem:
        gluster upgrade is not generating new volfiles

    Cause:
    During upgrade, "glusterd --xlator-option *.upgrade=on -N"
    is run to generate new volfiles. It is run post 'glusterfs'
    rpm installation. The above command fails during upgrade
    if geo-replication is installed. This is because on
    glusterd start 'gsyncd' binary is called to configure
    geo-replication related stuff. Since 'glusterfs' rpm is
    installed prior to 'geo-rep' rpm, the 'gsyncd' binary
    used to glusterd upgrade command is of old version and
    hence it fails before generating new volfiles.

    Solution:
    Don't call geo-replication configure during upgrade/downgrade.
    Geo-replication configuration happens during start of glusterd
    after upgrade.
