    Fix postrotate to notify holders of rotated logs

    Lsof +L1 locates unlinked and open files and does not work for
    logrotate, neither with copyteuncate not w/o that option.

    Instead, find *.X (X - number) files held and notify the processes
    owning those to make an apropriate actions and reopen new log files to
    stop writing to the rotated files.

    The actions to be taken by such processes are:

    * For httpd processes, use USR1 to gracefully reload
    * For neutron-server, restart the container as it cannot process
      HUP signal well (LP bug #1276694, LP bug #1780139).
    * For nova-compute, restart the container as it cannot process
      HUP signal well (LP bug #1276694, LP bug #1715374).
    * For other processes, use HUP to reload

    This also fixes the filter to match logfiles ending with *err,
    like rabbitmq startup errors log.
