Inventory/host_vars cleanup.

- hosts: remove gw-replacement2/3.local.netz and k1371.dyndns.org
  (duplicate of gw-ak.oopen.de).
- host_vars: move obsolete host directories to host_vars/DELETED/
  (devel-cloud, file-blkr-alt, file-ipa, ga-campus-gw-temp, ga-st-mm,
  gitea.so36.net, nc-gw, moodle, nscache, server16, server20, web-test,
  gw-replacement2/3/4).
- host_vars: fix file names (ga-al-gw-common.yml,
  gw-replacement.local.netz/gw-replacement-common.yml) and the header of
  mm-nd-test-ipt-server.yml.
