    glusterd: reject peer probe from a reinstalled node

    In a cluster if a node (say N1) goes through a OS reinstallation then
probing
    some other node in the cluster from N1 doesn't fail as in
    gd_validate_mgmt_hndsk_req () uuid & hostname checks are done separately
but
    there should be one more check where both the conditions should meet.

    Steps to create the problem
    - N1 probes N2
    - bring down glusterd instance on N2
    - remove /var/lib/glusterd/* from N2
    - restart glusterd instance on N2
    - execute gluster peer probe N1 from N2

    Validations in gd_validate_mgmt_hndsk_req () has been improved to handle
this
    special case
