nfs: Introduce rpc.register-with-portmap to disable portmap registration
For systems that need to run multiple nfs servers, we need to prevent more than one from registering with portmap service. Use this option to turn off portmap registration for Gluster NFS. Portmap registration is on by default. Signed-off-by: Shehjar Tikoo <shehjart@gluster.com> Signed-off-by: Anand V. Avati <avati@dev.gluster.com> BUG: 1743 (XenServer is not compatible with GlusterNFS) URL: http://bugs.gluster.com/cgi-bin/bugzilla3/show_bug.cgi?id=1743
