systemd: various updates and fixes
    
    Don't use lvmetad in lvm2-monitor.service ExecStop to avoid a systemd issue.
     - a systemd design issue while processing dependencies
       with socket-based activation that ends up with a hang
     - https://bugzilla.redhat.com/show_bug.cgi?id=843587
       (also tracker bug https://bugzilla.redhat.com/show_bug.cgi?id=871527)
     - not using lvmetad in this case is just a workaround, once the bug
       above is resolved, we should enable the lvmetad in that specific case
    
    Remove dependency on fedora-storage-init.service in lvm2 systemd units.
     - fedora-storage-init.service and fedora-storage-init-late.service is
       going to be separated into respective units that belong to each block
       device subsystem:
         - mpath + mdraid activated via udev solely
         - dmraid with its own dmraid-activation.service unit
         - lvm2 with the lvm2-activation-generator to generate the
           activation units runtime if lvmetad disabled
           (global/use_lvmetad=0 set in lvm.conf) and activation done
           via udev+lvmetad if lvmetad enabled (global/use_lvmetad=1 set
           in lvm.conf)
    
    Depend on lvm2-lvmetad.socket in lvm2-monitor.service systemd unit.
     - as lvm2-monitor uses lvmetad if lvmetad is enabled
