glusterd: import/export brickinfo->uuid

Backport of http://review.gluster.org/#/c/13047/ 

    Given a two node cluster with node N1 & N2, if a dummy node N3 is peer probed, the
    probed node N3  goes for importing volumes from the probing node (N1), but
    it still doesn't have information about the other node (N2) about its membership
    (since peer update happens post volume updates) and hence fail to update its
    brick's uuid. Post that even though N2 updates N3 about its membership the
    brick's uuid was never generated. Now as a consequence when N3 initiates a
    detach of N2, it checks whether the node to be detached has any bricks
    configured by its respective uuid which is NULL in this case and hence it goes
    ahead and removes the peer which ideally it shouldn't have (refer to
    glusterd_friend_contains_vol_bricks () for the logic)
    
    Fix is to export brick's uuid and import it at the probed node instead of
    resolving it.
