    Fix LVM2 PV shrinking with lvm2 2.02.171 and later (#1)
    
    Shrinking an LVM2 Physical Volume on CentOS 7 with the latest
    lvm2 2.02.177 fails like this:
    
      Shrink /dev/sda9 from 1.00 GiB to 768.00 MiB
      * calibrate /dev/sda9
      * check file system on /dev/sda9 for errors and (if possib...(SUCCESS)
      * shrink file system                                         (ERROR)
        * lvm pvresize -v --setphysicalvolumesize 786432K '/dev/...(ERROR)
            0 physical volume(s) resized / 1 physical volume(s) not resized
    
            Wiping internal VG cache
            Wiping cache of LVM-capable devices
            /dev/sda9: Requested size 712.00 MiB is less than real size 1.00 GiB.  Proceed? [y/n]:[n]
            Physical Volume /dev/sda9 not resized.
    
    This upstream change to lvm2 [1] makes pvresize prompt for confirmation
    whenever the --setphysicalvolumesize option is used.  (The change was
    included in lvm2 2.02.171 and later, which is used in recent
    distributions.  The reporter found the issue on Ubuntu 18.04 LTS and I
    reproduced the issue on RHEL/CentOS 7.5).  The set size option has to be
    used when shrinking the PV before shrinking the partition therefore fix
    this issue by adding lvm common option --yes when using the set size
    option.

        pvresize: Prompt when non-default size supplied.
    
    Closes #1 - Can't shrink LVM partition due to pvresize prompt
