exportfs: Add pseudo resource factor (bsc#978680)
    
    exportfs resource relies on output from exportfs utility which in turn
    stores its state data in /var/lib/nfs/etab. This file survives reboot
    (e.g. after fencing) and when probe monitor operation is invoked
    exportfs RA will report resource as *started* if there are respective
    records in /var/lib/nfs/etab despite the fact nfsserver resource is
    not started and exportfs resource is thus effectively *stopped*.
    
    Normally this is not a problem because nfsserver clears content of
    /var/lib/nfs/etab upon start, however, when only monitor operations are
    executed (e.g. probing after reboot) wrong state of exportfs resource is
    reported.
    
    This solution puts alleged status of the resource in logical conjunction
    with pseudo resource state (i.e. it's not pure pseudo resource, just
    necessary condition). The idea is from Dejan Muhamedagic
    <dmuhamedagic@suse.com>.
    
    Note: pseudo resource state is kept in $HA_RSCTMP directory, which is
    supposed to be empty after reboot.
