[DRBD-announce] linstor-server 1.20.3 release

Hi!

We fixed a few more minor bugs since the last patch release and thought it
is
worth it to release them before the next minor release.

Here are the changes:

### Changed

- pvdisplay now ignores drbd devices(lvm filter)
- Volume definition setSize checks now for out of bounds sizes

### Fixed

- Fixed typo in VDO slab size commandline argument
- Fixed peerslot check also counting diskless resources
- Fixed storage pool definition delete not checking if there are still
other storage pools
- Fixed resource definition create showing real exception because of a
followup exception
- Fixed resetting resource flags to now incompatible drbd resource flags
