How reproducible:
Always

Steps to Reproduce:
1.Create ganesha cluster setup
2. create a volume,start it
3. Execute gluster vol reset volname <any vol option>

Actual results:
It resets the ganesha enable option as well and brings ganesha and other
services to stopped state and pcs status shows all nodes stopped.

Expected results:
The volume reset for specific option should only reset taht option and should
not cause changes to ganesha related options and should not bring down the
cluster.

    glusterd/ganesha : handle volume reset properly for ganesha options

    The "gluster volume reset" should first unexport the volume and then delete
    export configuration file. Also reset option is not applicable for
ganesha.enable
    if volume value is "all".
    This patch also changes the name of create_export_config into
manange_export_config
